  34. Terrestrial Magnetism Studies
  35.  
  36. After the first flight by the 46th over the polar sea, the navigators on the flight recommended that
  37. an intensive study be made of the magnetic compass and its reliability in this area. One of the
  38. navigators in the flight made preparations to carry out such a study, but abandoned the project as
  39. flights did not go over enough area at that time to permit a complete survey. When “Project Polaris”
  40. got underway the opportunity for a complete study presented itself. First Lieutenant Frank O. Klein
  41.  
  42. accepted this responsibility and went all out in pursuit of definite information on magnetism. In
  43. Frank Klein’s own words:
  44.  
  45. “It all began when we were told in textbooks and by the authorities that any magnetic compass was
  46. useless in the Arctic. The magnetic compass was said to fluctuate wildly because of proximity to the
  47. north magnetic pole. But as is often the case, conventional wisdom was proven to be flawed.
  48.  
  49. “As chance would have it, I had been appointed the ‘Flight B Navigator‘, whose primary area of
  50. concern within the Arctic encompassed the islands of the Canadian Archipelago. This was the area
  51. within which the north magnetic pole was to be found.
  52.  
  53. “To my surprise, early flights in the fall of 1946 suggested that the fluxgate compass was not entirely
  54. useless. Although the indicator typically oscillated slightly in the region (2 to 3 degrees), the
  55. requisite sensitivity for directional indications appeared always to be given. Unfortunately, its
  56. navigational use was precluded since the magnetic variation (declination) values depicted on our
  57. charts were purely extrapolated values, could not be immediately corroborated, and obviously could
  58. not be relied upon. A plan of action suggested itself. I would ask our Flight B navigators to read and
  59. record the fluxgate compass indication every time a true heading value was obtained from the astro-
  60.  
  61. é compass. This procedure could be made optional for navigators in the other flights of our squadron.
  62. ; Since a great many polar flights were being planned, these flights could produce sufficient magnetic
  63. variation values to develop a reliable chart of polar isogonals. Such a chart would provide polar
  64.  
  65. _ navigators with a backup means of navigation, particularly in an emergency. At this time, a search
  66.  
  67. 'é: for the current location of the north magnetic pole was at best an afterthought; but the afterthought
  68. 31‘ ptovided a valuable by-product.

  77. ‘1‘“Since the contemplated project was not a part of our squadron’s assigned mission and would
  78. $1.. involve additional work for our navigators, I sought approval for the work plan from my immediate
  79. l ‘gmpetvisor, the Squadron Navigator, Norbert Zwicke, who, true to form, gave his approval and
  80. ignthusiastic support.

  82. ,1 __ THE DEVELOPMEN T OF AN ARCTIC MAGNETIC CHART
  83.  
  84. ‘ cient data had been collected and analyzed by the end of 1947 to prepare a chart depicting
  85. ‘1 ngonals north of the North American continental shelf to 85°N latitude and roughly from the
  86.  
  87. 178 World in Peril
  88.  
  89. western half of the Canadian Archipelago westward to the International Date Line. The chart
  90. reflected approximately 600 mean variation values computed from data recorded by a numberof ,
  91. navigators.
  92.  
  93.  
  94.  
  95. “The individual magnetic variation values were determined by comparing true headings obtaimd
  96. from an astro-compass with magnetic headings simultaneously obtained from the fluxgate compass.
  97. In a large percentage of the magnetic observations,readings were avenged over a two-minute period
  98. and compared with the true heading value existing at the mid-pet'iod of the observation. Conse-
  99. quently, the total of individual magnetic readings considerably exceeded 600. The chart was sectored
  100. into many areas, for each of which mean variation values were determined. The average probable
  101. error for the mean was calculated to be no more than three.
  102.  
  103. “The subject chart was published in Vol. 30. No. 2, TRANSACTIONS, AMERICAN GEOPHYSI-
  104. CAL UNION (AGU). for April 1949. In addition, the AGU extended its membership to the author.
  105. The Department of Commerce, U. 8. Coast Guard and Geodetic Survey also accorded recognition
  106. to the project in a letter to Lt. Klein stating, ‘...thc availability of the data and the chart have been
  107. of great specific value to this Bureau in preparing magnetic charts...‘
  108.  
  109. II. THE SEARCH FOR THE MAGNETIC NORTH POLE
  110.  
  111. “By mid-year 1947 sufficient data (1000 determinations) had been collected within the Canadian
  112. Archipelago to provide some surprising findings. For one, the fluxgate compass was responsive to
  113. the relatively weak horizontal component of the earth’s magnetic field in almost all of the region.
  114. The exception was a small elliptical-shaped area whose axis extended NW—SE from Boothia
  115. Peninsula to the Bathurst Islands, about the area of Montana, which is small compared to the
  116. 5,5(D,000 square miles of the Arctic ocean. Although magnetic readings were Sometimes possible
  117. within this area, they were often erratic and unreliable. However, sufficient data became available
  118. to yield unexpected and confusing results. From a navigational standpoint, it appeared we were
  119. confronted not with one, but with three magnetic poles. A more critical analysis became necessary.
  120. This analysis indicated that only one of the poles met the acid test of complete isogonal convergency.
  121. This was the central pole on northwestem Prince of Wales Island, at 73°30’N - 101°00‘W as reported
  122. at that time.
  123.  
  124. “The two foci of the ellipse, one on Bathurst Island and the other on Boothin Peninsula were
  125. particularly perplexing. Neither of the two indicated complete isogonal convergency. Of the two, the
  126. area on Bathurst Island was more complete in this respect. (Incidentally, the Air Force charts current
  127. at the time depicted the magnetic pole on Boothia Peninsula).l Then, too, we had experimented with
  128. a number of “homing” missions which had successfully “horned—in" on each of the two foci. This
  129. was particularly significant since it suggested that the two local poles could prove of singular
  130. importance in a polar navigational emergency. Furthermore, I had personally witnessed complete
  131. fluxgate indicator gyrations at only three locations on all of my missions in the Arctic - and these
  132. were very near or at the three subject locations. These conditions prompted the reference. to two local
  133. or secondary poles - one on the Bathurst Islands at 75°35’N - 103°30’W (the more dominant
  134. secondary pole) and the other on Roothia Peninsula at 70°40‘N - 97°20'W.
  135.  
  136. Terrestrial Magnetism Studies 179
  137.  
  138. “It was not long after these findings had been officially reported that we learned that a Canadian
  139. ground expedition had been sent into the Canadian Archipelago with the specific mission of locating
  140. the position of the north magnetic pole. This expedition could not confirm our indications of
  141. secondary poles on Boothia and Bathurst. However, a letter dated July 21, 1948, written by R. Glenn
  142. Madill, Chief of Terrestrial Magnetism, Department of Mines and Resources, Canada, addressed to
  143. Lt. Frank O. Klein stated, ‘...However, we agree on one point and that is the presence of what we
  144. can call the main magnetic pole on northwestern Prince of Wales Island. I have accepted as a purely
  145. preliminary value the position latitude 73°N and longitude 100°W. Your value of 73°15’N and
  146. 99°45’W is in excellent agreement, and I suggest that you use your value by all means...’ This is
  147. astounding! Being just a few miles from the ground expedition’s results!”
  148.  
  149. A United States Air Force nationwide press release on October 19th, 1947 announced the discovery
  150. of the three magnetic north poles — unfortunately without qualification. Although Frank Klein was
  151. never accorded any formal recognition from the USAF for his efforts, he nevertheless has remained
  152. thankful for the fortune of having been a member of the 72nd Recon Squadron (VLR) Photographic.
  153. It was only by virtue of his havin g been an Air Force member of that unit, that aerial terrestrial
  154. magnetic research in the Arctic was made possible.
  155.  
  156. In the words of lst Lt. David J . Haney, another outstanding navigator in the squadron and author of
  157. Navigation North of Seventy: “As is so often the case, Klein’s co-workers did not always appreciate
  158. the hours of study and hard work he did on this project. His findings, probably more than any other
  159. single project, have been responsible for the attention focused on the organization by scientific
  160. agencies The much-deserved recognition for his work came when he was invited to accept
  161. membership in the American Geophysical Union. This honor is not only a hard-eamed recognition
  162. for Klein, but also for the squadron and the Air Force.”

  166. Clues to a Cataclysm
  167.  
  168. Frank O. Klein’s pinpointing of the north magnetic poles’ locations at positions 125 to 200 miles
  169. further north than was earlier predicted attracted great interest in the scientific community,
  170. particularly among top government scientists under Vannevar Bush. Since 1831, when the first
  171. observations were made, the magnetic north pole had remained almost static on Boothia Peninsula
  172. until 1945 (from 70°06’N-96054‘W 70°30’N-96000’W). Klein’s discovery in 1948 that the main
  173. magnetic north pole had moved to the northwestern shore of Prince of Wales Island (73°15’N—
  174. 99°45’W) revealed that it had dramatically moved 165 miles closer to the geographic north pole.1
  175. The government scientists subsequently began a scientific investigation into the ramifications of
  176. Klein’s findings. Many of their study groups, held at the Pentagon, were attended by Major White
  177. and Dr. Paul Siple.
  178.  
  179. The first determination of the Pentagon study was that while the rate of northward magnetic polar
  180. movement (which Dr. Paul Siple sought to establish) seemed to be unpredictable, it had been in a
  181. decidedly north—north-westerly direction, moving ever closer to the geographic North Pole. The
  182. question in the minds of many in the scientific community was what would happen if and when the
  183. magnetic pole converged on the geographic pole. Was there a connection between the powerful
  184. geomagnetic forces involved in polar movement and the mechanism that caused geologic change?
  185.  
  186. The forces that. have created mountains have remained a mystery, and yet there has to be an
  187. explanation for high strata of mountain rock containing marine fossils. Some tremendous force had
  188. to lift up the land with such pressure so as to raise former sea beds to high altitudes. There must be
  189. some reason why “beaches” of sand formed from ocean—wave action are found at lSOO—foot altitudes
  190.  
  191. in the mountains of Italy.2 Scientists have not yet been able to agree on whether the change that raised
  192. the sea beds was slow or rapid.
  193.  
  194. Spitzbergen is an island well within the Arctic Circle, and is now snow and icebound most of the year.
  195. Yet on Spitzbergen there is ample evidence that tropical corals once grew on the shores of the island.3
  196. Spitzbergen also has considerable coal deposits, attesting to the island’s once-temperate or tropical
  197. climate. Also found there were numerous fossils of water lilies imbedded in lignite, also confirming
  198. that the island once had a warm and marshy environment." How can we explain the oncc-temperate
  199. climate of this arctic region unless either the whole earth was once warmer than it is now, or unless
  200. the poles were in a different location relative to the earth’s crust?
  201.  
  202. WhenAdmiral Byrd went to the Antarctic from 1933 to 1935 , his expedition found leaf stein imprints
  203. and fossilized wood under the snow and ice.’ Sir Ernest Shackleton found coal beds within 200 miles
  204. of the geographic South Pole, evidence of massive primeval forestation in i’mtarctica.6 The
  205. explanation is not as obvious as saying that the Antarctic was once devoid of ice so that the plants
  206.  
  207. 182 World in Perl]
  208.  
  209. and forests could grow. We still must account for the fact that massive forestation doesn't occur
  210. where there are six months of darlmess during the year, a characteristic of a polar area.
  211.  
  212. Also found near the geographic South Pole were the fossilized footprints of a prehistoric mammal-
  213. like reptile.’ Since reptiles are known to be cold-blooded, and need the warmth of the environment
  214. to smtain their body heat, it is eVident that the Antarctic did not always have a cold climate. If this
  215. is true, Antarctica could not have always been located at the south geographic pole.
  216.  
  217. Although the phenomena referred to as Ice Ages are an accepted fact, few scientists canagree on how
  218. they are caused. N at only have mile-high ice sheets covered the northern North American continent
  219. as far south as. New Jersey, Ohio and Wiscomin; but Europe, Africa and India have had their ice ages
  220. too. There are many theories as to how they are caused, but none have been proven. We are left with
  221. numerous explanations, some plausible, and some improbable. The last Ice Age is believed to have
  222. ended only about 10,000 years ago, leaving many mysteries unsolved.
  223.  
  224. Millions of animals were frozen alive by the sudden glacial conditions of the last ice age, and
  225. hundreds of thousands have been found as they died, buried frozen in the ground. The New Siberian
  226. Islands, located 200 miles off the northern coast of Siberia, are almost literally composed of the
  227. bones and remains of multitudes of prehistoric mammoths, saber—toothed cats, giant beavers (the
  228. size of goats), prehistoric rhinoceros, buffalo, deer, horses, and other small mammals.“ How could
  229. so many of these animals (also found throughout Siberia and Alaska) be frozen intact within the
  230. ground in such a way that ten thousand years later their flesh, when thawed, was said to be “edible"?
  231. Indeed, at one Russian scient'st’s banquet the main course consisted of quite palatable mammoth
  232. steals.’Anotherquestion is how the tundra of northern Siberia and Alaska could have supported such
  233. large populations of prehistoric animals, unless the Arctic once had a temperate climate with lush
  234. vegetation?
  235.  
  236. It is well-lmown that tree rings are a measure of tree growth over annual seasons. Why then do
  237. prehistoric frozen tree trunks unearthed in Spitzbergen, Norway, have no rings? ‘° Only if there were
  238. once no seasons in Spitzbergen would the trees have no rings. But the only place on earth where there
  239. at e no seasons is at the equator. If the earth's equator once passed through or near Spitzbergen, then
  240. it is obvious that, relative to the earth’s crust, the earth’s geographic poles would once have to have
  241. been in ditterent locations than they are now. What caused their apparent shift?
  242.  
  243. An expedition digging in the Canadian Archipelago only a few hnndned miles from the geographic
  244. North Pole found under the ice and snow hundreds of frozen (not petrified) prehistoric tree trunks,
  245. shattered as though by massive tidal wave activity. and buried in the sand. Beneath the surface they
  246. found another layerof similar tree trunks, and beneath that layer yet another, until they had identified
  247. nine different levels of evidence of catastrophic change." Not only was the Arctic apparently once
  248. a highly forested temperate or tropical region, but It was subject to periodic cataclysmic upheavals.
  249.  
  250. It is clear that there have been times in the earth‘s history when geologic change has upset the living
  251. conditions of its flora and fauna. Many examples argue that such changes are violent and dramatic.
  252. As Professor Frank C. Hibben points out in his book The Lost Americans:

  257.  
  258. The Alaskan muck is like a fine, dark gray sand...Within this mass, frozen solid, lie
  259. the twisted parts of animals and trees intermingled with lenses of ice and layers of
  260. peat and mosses. It looks as though in the midst of some cataclysmic catastrophe of
  261. ten thousand years ago the whole Alaskan world of living animals and plants was
  262. suddenly frozen in midmotion in a grim Charade...
  263.  
  264. Throughout the Yukon and its tributaries, the gnawin g currents of the river had eaten
  265. into many a frozen bank of muck to reveal bones and tusks of these animals
  266. protruding at all levels. Whole gravel bars in the muddy river were formed of the
  267. jumbled fragments of animal remains...
  268.  
  269. The Pleistocene period ended in death. This is no ordinary extinction of a vague
  270. geological period which fizzled to an uncertain end. This death was catastrophic and
  271. all—inclusive... The large animals that had given their name to the period became
  272. extinct. Their death marked the end of an era.
  273.  
  274. But how did they die! What caused the extinction of forty million animals? This
  275. mystery forms one of the oldest detective stories in the world. A good detective story
  276. involves humans and death. These conditions are met at the end of the Pleistocene.
  277. In this particular case, the death was of such colossal proportions as to be staggering
  278. to contemplate.l2
  279.  
  280. lf life on earth can be subject to such wholesale destruction, there is much to be said for learnin g all
  281. that we can about the geological forces involved.

  297. Field of study: Geomagnetism and paleomagnetism
  298.  
  299. Evidence from several of the earth sciences clearly demonstrates that the earth is magnetic and
  300. geographic poles have been located at widely separated places relative to its surface during the
  301. planet is geological history.

  321.  
  322. PLATE TECTONICS: the study of the motions of the earth’s crust.
  323. Summary of Phenomenon
  324.  
  325. Shortly before World War H , geophysicists discovered a method of determining the location of rocks
  326. on thelearth’s surface at the time they were formed, relative to the north magnetic pole. Thus began
  327. the study of paleomagnetism. Paleomagnetic studies quickly yielded very puzzling and often
  328. contradictory results. The new science produced evidence that the north magnetic pole has changed
  329.  
  330. 186 World in Peril
  331.  
  332. its location by thousands and even tens of thousands of miles hundreds of times during the earth’s
  333. geologic history. Since earth scientists are generally agreed that the north magnetic pole has always
  334. corresponded closely with the north geographic pole, this evidence seemed to indicate that the
  335. earth‘s axis of rotation must have changed, a highly unlikely occurrence.
  336.  
  337. As the paleomagnetic evidence for different locations of the poles in the past accumulated through
  338. measurements of rock formations from around the world, more and more earth scientists began to
  339. accept the theory of continental drift. This theory offered an explanation of the paleomagnetic
  340. evidence without the necessity of postulating that the earth‘s axis of rotation had changed in the past.
  341. Alfred chcncr, early in the twentieth century, had drawn attention to the theory that the continents
  342. moved in relation to one another. Most geologists initially gteeted his theories with derision, but
  343. many others agreed with him, causing an often bitter controversy in the earth sciences that lasted
  344. almost half a century. The ever—growing body of paleomagnetic eVidence could be explained by
  345. postulatitm that the surface areas of the earth move in relationship to the planet‘s axis of rotation.
  346. This explanation proved to be more acceptable to geologists than the idea that the axis of rotation
  347. changed.
  348.  
  349. With the growing acceptance of the theory of continental drift in the 1940's, geologists began trying
  350. to explain the mechanism that caused it. They postulated that the earth has a stable and very dense
  351. core overlain by an area called the asthenosphere, which ismade up of rock rendered plastic by heat
  352. and pressure. Floating on the asthenosphete is the earth‘s outer crust, or lithosphere. Dislocation
  353. within the earth caused by the action of heat and pressure teeult in the movement of the lithosphere
  354. relative to the core and to the axis of rotation. The initial attempts to explain continental drift have
  355. been considerably revised and refined into the modem theories of plate tectonics and ocean-bed
  356. spreading, but the basic premise remains the same: The surface areas of the earth move in
  357. relationshi p to its core and to its axis of rotation. The result of the movement of the earth’s lithosphere
  358.  
  359. is that the surface area located at the axis of rotation does not remain the same over long periods of
  360. time. This shifting accounts for the apparent “wandering” of the poles as well as for several other
  361. puzzling aspects of earth‘s geologic history.
  362.  
  363. Suiking evidence that the surface areas of the earth have moved enormous distances during geologic
  364. history relative to its axis of rotation coma from the study of glaciers. Observations from around
  365. 'he globe show thatalmost all the land areas of the earth have been glaciated at some time in the past,
  366. including parts of Africa, India, and South America presently located on or near the equator. Without
  367. postulatin g either a substantial shifting of the earth‘s surface relative to its axis of rotation or a change
  368. in the axis, equatorial glaciation is inexplicable. If global temperatures dropped to levels sufficient
  369. to glaciate even the equator at some time in the past, all life on earth would have been destroyed. If,
  370. however, the areas of Africa, India, and South America which are presently located in tropical locales
  371. once shifted to the polar regions and shifted from there to their present locations, their ancient
  372. glaciation is not at all mysterious.
  373.  
  374. Shifting of the earth 3' surface relative to its axis of rotation is almost certainly a major cause of the
  375. so-called ice ages, the origins of which have puzzled glaciologists since the beginnings of that
  376. science. Previous explanations of ice ages - including global drops in temperature, the passage of
  377. the earth through exceptionally cold regions in space or through areas containing “spacedust” that
  378.  
  379. Polar Wander 187
  380.  
  381. blocked out a significant amount of the sun’s radiation. and unexplained fluctuations in the amount
  382. of radiation generated by the sun - are all unsatisfaetory. It seems much more likely that areas of the
  383. eanh that were glaciated in the past, such as northem Europe and North America as far south as
  384. present-day New Jersey, were located much closer to one or the other of the poles at the time they
  385. were covered with ice.
  386.  
  387. The study of pnleoclimatology has also produced evidence supporting the proposition of the shifting
  388. of the earth’s crust relative to its axis of rotation. Paleoclimatologists study the climates of past ages
  389. on the various parts of the earth‘s surface. They have found that Antarctica once supported rich
  390. varieties of plant and animal life, many of which could only have lived in temperate and even
  391. subtropical climates. Explorations in the. far nnrthem regions of Canada, Alaska, and Siberia have
  392. revealed that those areas also supported multitudes of animals and luxurious forests in the past, as
  393. did many of the islands presently located within the Arctic Circle Obviously, these regions must
  394. have had much warmer climates at the times when the plant and animal life flourished there, which
  395. can be explained in only one of two ways: either the climate of the entire world was much warmer
  396. in the past, or those areas now located near the poles were once located in much more temperate
  397. latitudes. If the entire world had warmed to the point that the polar areas had temperate climates, the
  398. tropical and subtropical areas of the earth would have been much too hot to support life, which is
  399. demonstrably untrue according to the fossil record. Thus, the areas now near the poles must have
  400. been located in temperate climatic latitudes in the past.
  401.  
  402. Earth scientists, using the evidence discussed above and paleomagnetism, have established an
  403. approximate chronology showing which areas of the earth's surface were located at its north
  404. rotational axis during past ages. At the beginning of the Cambrian period (roughly 600 million years
  405. ago). the atea of the Pacific Ocean now occupied by the Hawaiian Islands was at or near the earth’s
  406. north rotational axis. By the Ordovician period 100 million years later, the surface of the earth had
  407. shifted in such a manner that the area approximately 1,000 miles north and east of modem J apan was
  408. on or near the N orth Pole. Fifty-five million years later, during the Silurian period, modem Sakhalin
  409. Island north of Japan was within the Arctic Circle. During the next 20 million years, the area of
  410. modem Kamchatka in eastern Siberia shifted to a position very near the Pole. Earth scientists have
  411. identified ninety-nine separate locations that occupied the polar regions at one time or another
  412. during the ensuing 395 million years from the Silurian to the Pleistocene. During the past million
  413. years, forty-three different areas of the earth's surface have been on or near the north geographic
  414. poles, averaging over 1,500 miles distance from each other.
  415.  
  416. Although contemporary earth scientists have reached a consensus that the surface of the earth has
  417. shifted relative to the planet‘s axis of rotation many times in the past, several problems remain. One
  418. area on which there i: no unanimity of opinion i: the mechanism responsible for crustal shift. The
  419. answer most likely lies in high-pressnre physics and the nature of the asthenosphere. Another. more
  420. controversial, problem concerns the speed ofcrustal shtfis. During most of the twentieth century,
  421. almost all of the geologists who were daring enough to accept the theory of continental drift assumed
  422. that the movement of surface features of the earth relative to the axis of rotation and relative to one
  423. another was very slow, on the order of a few inches per year at most. Then an increasing number of
  424. earth scientists began arguing for short periods of relatively rapid movement of the earth’s crust and
  425. long pedods of stability.
  426.  
  427. 188 World in Peril
  428.  
  429. Those problems notwithstanding, there can no longer be any doubt that the surface of the earth has
  430. shifted many times relative to its rotational axis. The phenomenon has led to the mistaken
  431. assumption that the rotational axis has moved relative to the earth’s surface - thus the term “polar
  432. wander.” The rotational axis of the earth has remained constant throughout its history; apparent polar
  433. wander is caused by the shifting of the earth’s crust.
  434.  
  435. Methods of Study
  436.  
  437. The study of paleomagnetism during the twentieth century has yielded irrefutable evidence that
  438. many different areas of the earth’s surface have occupied polar positions during the history of the
  439. planet. Scientists studying paleomagnetism measure the weak magnetization of rocks. Virtually all
  440. rocks contain iron compositions that can become magnetized. In the study of paleomagnetism, the
  441. most important of these compositions are magnetite and hematite, which are commonly found in the
  442. basaltic rocks and sandstones. Paleomagnetlsm may also be measured in less common rocks that
  443. contain iron sulfide. In i gneous rocks, magnetization takes place when the iron compositions within
  444. the rocks align themselves with the earth’s magnetic field as the rocks cool. In sedimentary rocks,
  445. small magnetic particles align with the magnetic field as they settle through the water and maintain
  446. that alignment as the sediments into which they sink solidify.
  447.  
  448. Magnetized rocks not only indicate the direction of the north magnetic pole at the time they were
  449. formed, but also show how far from the Pole they were at formation by the angle of their dip.
  450. Scientists call their horizontal angle of variation and their dip, the inclination. Variation reveals the
  451. approximate longitude of the rock sample at the time of its formation, relative to the north magnetic
  452. pole, and inclination gives its approximate latitude. By ascertaining the date at which the roclt
  453. sample being examined was formed, using well—known methods, scientists are able to establish the
  454. area of the earth’s surface relative to the north magnetic pole that was occupied by the rock at the
  455. time of its formation.
  456.  
  457. There are, however, many pitfalls for the unwary scientist investigating paleomagnetism. A rock
  458. whose magnetism is being studied may have moved considerable distances from its place of
  459. formation by glacial action or by crustal movement along a major fracture in the earth's surface, such
  460. as the San Andreas fault on North America‘s west coast. High temperatures, pressure, and chemical
  461. action can dzstort or destroy the magnetization of a rock Folding and the movement of the continents
  462. relative to one another may also alter the original orientation of the rocks whose magnetism is being
  463.  
  464. studied. All thm pitfalls may be avoided through the expedient of basing estimates of the relative
  465. position of the north magnetic pole on a great number of rock samples of the same age, gathered from
  466. many different locations on all the continents.
  467.  
  468. Another problem in paleornagnetic studies involves the constant movement of the north magnetic
  469. pole relative to the north geographic pole. Recent studies show that the north magnetic pole moved
  470. from 70 degrees to 76 degrees north latitude (approximately 345 miles, or 576 kilometers) during
  471. the period 183 1-1975. This phenomenon might accurately be called true polarwander, though it does
  472.  
  473. Polar Wander 189
  474.  
  475. not involve any alteration either of the earth's axis of rotation or of the surface of the planet relative
  476. to its axis of rotation. More geophysicists studying this movement have concluded that over a period
  477. of several thousand years, the average position of the north magnetic pole coincides with that of the
  478. north geographic pole. Thus, when scientists learn that the north magnetic pole was located near
  479.  
  480. Hawaii 600 million years ago, it is a virtual certainty that modern Hawaii was at that time located
  481. near the north geographic pole.
  482.  
  483. Context
  484.  
  485. The most immediate and pressing questionfacing all residents of planet Earth concerning apparent
  486. polar wonder is the speed with which the phenomenon may occur. An historian of science, Charles
  487. H. Hapgood, compiled a huge amount of compelling evidence in the 1950’s that massive shifts of
  488. the earth‘s crust relative to its axis of rotation occur in geologically brief periods of time. Hapgood
  489. made a very strong case for the surface area of the Canadian Yukon, which is now located at
  490. approximately 62 degrees north latitude, and longitude 137 degrees west, having occupied the north
  491. geographic pole prior to 80,000 years ago. Then, in a massive movement which took less than 5,000
  492. years, the earth’s surface shifted in such a way that an area of the Greenland Sea now located at
  493.  
  494. approximately 72 degrees north latitude, and longitude 10 degrees east occupied the north polar
  495. region. This shift involves a distance of almost 5,000 miles.
  496.  
  497. Hapgood offers further evidence that the earth’s surface remained stable relative to its axis of rotation
  498. for approximately twenty thousand years, then began another massive shift resulting in the area of
  499. Hudson‘s Bay that now occupies the surface region located at about 60 degrees north latitude, and
  500. longitude 83 degrees west, moving to the earth‘s north rotational axis. This movement of
  501. approximately 3,500 miles took less than 5,000 years. Again the earth‘s surface became stable,
  502. according to Hapgood, this time for more than 30,000 years, until about 17,000 years ago. At that
  503. time, the earth‘s surface began another movement lasting nearly 5,000 years and resulting in the
  504. present surface-pole relationship.
  505.  
  506. If Hapgood is right about the surface of the planet shifting enormous distances in relatively short
  507. periods of time, the period during which the shift actually occurs must be a traumatic era for the
  508. earth's flora and fauna, including humankind. Such rapid movement would certainly produce
  509. earthquakes and volcanic action of almost unimaginable proportions throughout the globe. Weather
  510. and tidal patterns would be greatly and unpredictably altered, which could have fatal consequences
  511. for many plant and animal species. The last result offers yet another piece of powerful evidence for
  512. the rapid-shift hypothesis.
  513.  
  514. The earth’s fossil record offers examples of the mass extinction and extermination of many species
  515. of flora and fauna during the geological history of the planet. The most recent such event occurred
  516. at the end of the Pleistocene epoch, about 12,000 years ago. Literally tens of millions of animals in
  517. North America alone died in a relatively short period of time, leaving their sometimes remarkably
  518. well-preserved remains lumped together in huge “boneyards,” stretching geographically from
  519. Alaska to Florida. This mass extinction of fauna must have been caused by the events accompanying
  520.  
  521. 190 World in Peril
  522.  
  523. crustal displacement: volcanic action on a gigantic scale not only would throw huge amounts of ash
  524. into the air, causing a lowering of global temperatures and an increase in rainfall producin g
  525. widespread flooding, but would also produce quantities of poisonous gasses lethal to animals and
  526. humans in the vicinity; rapid and pronounced weather changes would destroy food supplies which
  527. may have been the ultimate cause of the extinctions of many species; widespread earthquakes could
  528. also take a large toll on animal life.
  529.  
  530. If, as more and more geophysicists are comin g to believe, the shifting of the earth’s surface does ta ke
  531. place rapidly at infrequent intervals and for reasons not currently well understood, the phenomenon
  532. is of the utmost importance. Modern civilization would not survive the enormous climatic
  533. dislocations that must accompany such a shift. It is therefore imperative that the phenomenon known
  534. as polar wander be studied to the point that it can be, if not prevented, at least predicted and prepared
  535. for.
  536.  
  537. Chapter 30
  538.  
  539. The Flip of the Earth
  540.  
  541. Washington Post: (October 7, I946) — “General George C. Kenney [Commander
  542. of Strategic Air Command]: ‘Apparently the magnetic North Pole is about 200
  543. miles closer to the North Pole than was previously believed. ”’
  544.  
  545. In the previous chapter Frank N. Magill points out (1) that polar wander has occurred in the geologic
  546. past, (2) that polar wander is caused by the shifting of the earth’s crust, (3) that the magnetic pole
  547. has wandered, (4) that polar wander is almost certainly a major cause of catastrophic geologic
  548. upheavals and ice ages; however, (5) the “mechanism" responsible for crustal shift remains
  549. unknown, and (6) the speed of crustal shift is not known but would determine the consequences to
  550. civilization and the world‘s flora and fauna.
  551.  
  552. Although contemporary science raises numerous questions, many of their answers may have been
  553. found by government scientists and geographers almost forty—five years ago. The data on terrestrial
  554. magnetism that the 46th/72nd Squadron obtained indicated that the magnetic pole was 125 to 200
  555. miles north of where it was predicted to be accordin g to proj ections from findings obtained on earlier
  556. expeditions. This indicated that the north magnetic pole had moved toward the geographic pole
  557. much faster than previously anticipated. Among the government scientists, the question arose as to
  558. what would happen when the magnetic and geographic poles coincided.
  559.  
  560. To answer this, under the project control of Dr. Paul A. Siple, the Remington Rand Corporation was
  561. contracted to conduct lab studies using models of the earth constructed of concentric spheres - an
  562. inner sphere representing the electromagnetically-charged molten iron core of the earth whose axis
  563. defined the “magnetic” poles; and an outer sphere representing the crust of the earth which rotated
  564. around a “geographic” polar axis. It was determined through repeated experimentation that as the
  565. “magnetic” pole approached the “geographic” pole, the “magnetic” pole would at some point.
  566. accelerate its rate of convergence as though pulled toward the “geographic" pole by centrifugal force
  567. and jump to coincide; but instead of the poles coinciding, the “magnetic” pole would rapidly “flip”
  568. around the “geographic” pole, then spin off towards the equator as though by centripetal force,
  569. ending up at a position where the two axes assumed an approximate 89 degree divergence. After this
  570. polar “flip" occurred, the axes would then gradually begin to reconverge over a Ion g period of time.
  571.  
  572. Using the experimental model as an indicator of what happened and could happen on our planet, we
  573. might better be able to understand the earth‘s geologic history. If indeed during the polar flip process
  574. not only is the magnetic pole displaced to some indeterminate point on the face of the earth, but the
  575. geomagnetic stress causes the crust to shift in some direction away from the static rotational axis of
  576. the earth, it could explain the apparent re pos itionin g of the geographic pole. If, as Hapgood su g gests,
  577. the previous position of the geographic pole was in the Hudson Bay area, it would explain the once-
  578.  
  579. 192 World in Peril
  580.  
  581. warmerclimates of Siberia and the Arctic Ocean, which were only interrupted by freezing conditions
  582. when the geographic pole assumed its present position, turning the northern steppes into arctic
  583. tundra and freezing the inhabitants.‘ Similar cataclysms have apparently happened throughout the
  584. geologic past, when the geographic North Pole was located not only in California, Hawaii, and off
  585. the coasts of Russia and Japan, but even in South Africa.2
  586.  
  587. The question of how fast this phenomenon might occur is anall-important one. Aclue tothis mystery
  588. may have been found at Fairbanks Creek, on the outskirts of Fairbanks, Alaska in 1948. During
  589. sluicing operations while mining for gold, 3 team was thawing and washing away the permafrost to
  590. get to the gold ore at bedrock level when they uncovered the frozen remains of a young (first year)
  591. mammoth, Unearthed were the remarkably well-preserved head, trunk and front leg of the animal
  592. which paleontologists soon named “Effie”. Two interesting aspects of the Frown fauna were evident.
  593. The lush vegetation in its mouth and carbon-dating analysis indicated that the animal had died during
  594. the growing season in an apparently warm climate 20,000 to 22,600 years ago.’ And secondly, the
  595. animal had been frozen immediately after death, since its flesh was said to be edible. For some
  596. reason, a mammoth foraging in the summertime or early fall was almost instantaneously frozen and
  597. remained so for at least twenty millennia. More perplexing is how a freshly-killed and frozen animal
  598. could be found deep in the permafrost. Perhaps the most Likely explanation is that Effie, like so many
  599. other prehistoric animals, was killed and buried by an unseasonal, subfreezlng glacial loas- or silt-
  600. storm, accompanied by a major, pennancnt climatic change.
  601.  
  602. Another curious observation occurred during an archaeological dig at the remains of a “sunken”
  603. prehistoric tropical lake community between Nome and Kotzebue. Alaska. While digging in the
  604. permafrost among the remains of the lake community, an archaeologist unearthed a mosquito in a
  605. piece of ice from the 10,000 year old strata, and set it in the sunlight to thaw. Shortly after the ice
  606. had melted, the mosquito stretched its wings and then flew away.‘ Apocryphal as it may sound, this
  607. event corroborates our previous observation. Modern cryogenic studies have indicated that in order
  608. for a living creature to be successfully revived after being frozen for such a long period of time, it
  609. would have to have been frozen instantaneously! Normal climatic freezing would have caused ice
  610. crystals to grow within the creatures cells and tissues, rupturing the membratm and causing the
  611. animal ‘5 destruction. Therefore, the conclusion would seem inescapable that something cataclysmic
  612. caused these instantaneous freezings of temperate or tropical regions and their inhabitants. Arapid
  613. crustal shift of lower-latitude land masses into the Arctic would explain these observations.
  614.  
  615. The polar-flip phenomenon may indeed be the triggering “mechanism" of polar or crustal shift, and
  616. explain how the magnetic pole has been displaced so radically and rapidly in the past. It could also
  617. provide some explanation for the tremendous geomagnetic forces that cause the crustal shift itself.
  618. If the geomagnetic field of the earth is created by the motion of its charged molten nickel and iron
  619. core, its revolving electromagnetic force may possibly produce a dynamic effect when interacting
  620. with the earth‘s rotational axis. Needless to say, further study in this area might lead to a better
  621. understanding of the dynamics involved.
  622.  
  623. Crustal shift, as an explanation for the geologic upheavals of the past, would also account for the
  624. fantastic tectonic stresses that are the probable causative factors in the formation of new mountain
  625. ranges During a scientific meeting at the Pentagon, it was discussed how the flip phenomenon

  635. 194 World in Peril
  636.  
  637. would cause a “cooling efl'ect‘, followed by a bilateral “contraction” of the earth and the formation
  638. of another “ring of mountain ranges around the planet”. Counting the existing chains of mountain
  639. ranges of this ty pe on land and within the oceans ,they concluded that at least five major polar “flips”
  640. had occurred in fairly recent geologic history.
  641.  
  642. Polar shift could have other dramatic geologic consequences In the previous chapter, Frank Magill
  643. says, “shifting of the earth's surface relative to its axis of rotation is almost certainly a major cause
  644. of so-called ice ages . It Is known that there is a narrow margin between the temperatures of glacial
  645. and interglacial ages, usually considered not more than 6 degrees Centigrade. If the polar caps and
  646. arctic air masses were to be transpormd to lower latitudes due to crustal shift, not only would the new
  647. polar areas rapidly cool, receiving less solar radiation, but the phenomenon could set into motion
  648. (or “trigger") a progressive cooling effect. Some experts believe that under these circumstances
  649. “positive feedback" would take place as the increased snow and ice-covered terrain reflected more
  650. and more of the sun’s warming rays, with “a little cold begetting more of the same”, until the planet
  651. was locked into another ice age.“
  652.  
  653. There have been many attempts to determine if ice ages occur in cycles, and if so, when the next one
  654. could be expected to begin, namely the astronomical theory, Croll‘s Theory, Milankovich‘s
  655. approach, and core samplings, to name ai’ew.7 Ifcrustal shift is interrelated with the onset of ice a ges,
  656. then the recurring patterns of ice ages should help us predict crustal shifts. For example, one ice age
  657. theory based on earth strata studies indicates that following each ice age, bread-leafed deciduous
  658. trees cover the earth, followed after many thousands of years by conifers, later by grasslands, and
  659. finally by wind-blown silt ot' the next glacial age Repeated layers of this soil strata combination
  660. suggests a predictable cyclical pattern. “On the basis of this definition the present interglacial age
  661. - the Holocene Epoch - began about 10,000 years ago...and can be expected to end within the next
  662. 2,000 years.” This estimate correlates very closely with that of the government scientists, who
  663. predicted that the next “flip” of the earth could occur any time between 17 and 1,0“) years of the
  664. date of their study, which was conducted in 1947. The scientists could not further narrow the time
  665. parameters for occurence because they knew of no feasible way, in 1947, to accurater calculate the
  666. mass of the earth relative to the mass of its crust.
  667.  
  668. Just as a toy top or a gyroscope will occasionally wobble under certain circumstances, apparently
  669. the earth too has periodically “toppled” when its poles sought to converge, causing its crust to make
  670. dramatic shifts off the polar axis. It is possible that along with accompanying violent weather
  671. changes and massive tidal waves that could immdate land masses, there would undoubtedly also be
  672. earthquakes and volcanic activity along the tectonic plates and within new mountain range
  673. formations. Sufficient volcanic activity could cloud the atmosphere, further reducing the global
  674. temperatures and accelerating the onset of glacial conditions. N eedless to say, a post-flip environ-
  675. ment would undoubtedly be a hostile one.
  676.  
  677. It is possible that the pular-l'lip theory could also explain other observations. It could indeed be the
  678. predominant natural phenomenon rmponsiblc for the reshaping of our planet. Not only would the
  679. theory explain mass extinctions, but it may provide a basis for understanding the stages of
  680. evolutionary progression. It is fairly well recognized that there is no scientific evidence to i ndimte
  681. smooth evolutionary transitions from more primitive species to more advanced ones. In fact, studies
  682.  
  683. The Flip of the Earth 195
  684.  
  685. indicate that each new species seems to have come into existence all of a sudden, almost as though
  686. they were created.
  687.  
  688. Hostile conditions following a flip might produce an environment in which only the most adaptable
  689. species would survive. It is easy to speculate that such conditions may have brought about the
  690. extinction of Neanderthal Man, who may have been faced with nmorc difi‘icult and complex survival
  691. situation than his reasoning skills could cope with.
  692.  
  693. At the same time, the budding strain of Cro-Maguun man, with a greatet cranial capacity and more
  694. adaptability, may have much more easily adjusted to the demands of a hostile environment and thus
  695. emerged as Modern Man. Possibly stimulated and challenged to overcome the conditions caused by
  696. a flip, he became the most fitting creature to dominate the earth. In past history, when competitors
  697. or biological pressures were eliminated by catastrophic change, oftentimes those species more
  698. suited to adaptation underwent a form of explosive evolution to fill the biological gaps.“
  699.  
  700. Perhaps, with another geological upheaval facing us, we are now once again on the verge of a new
  701. quantum leap in what we might call “creative evolution”, or transitioning to the next higher stage
  702. in human development. With a more developed intelligence, potential to learn and capacity for
  703. invention, we may be even better suited to manage our survival and direct our destiny than any
  704. creature that has faced catastrophic change in the past Although, while we have the capacity to
  705. survive, the issue is whether we have the will and the wisdom to plan and prepare for what the future
  706.  
  707. may bring. Not only does the viability of our civilization hang in the balance, but so does the very
  708. future of our species.
  709.  
  710. Practically all of the experiences of the 46th/72nd Recon Squadron would be duplicated in major
  711. portions of the world in the event of a geological cataclysm. Knowledge of how to build or rebuild
  712. a home with scarce materials would be useful. In addition, finding available natural food sources
  713. would also be beneficial, as would the ability to conduct successful search and rescue efforts, though
  714. on a larger scale. Training in arctic survival would be critical for certain, as of yet undetermined,
  715. areas of the globe, as well as an understanding of transportation maintenance in subfreezing
  716. climates. Our education systems clearly need to foster not only the natural curiosity needed to solve
  717. complex survival and reconstruction problems, but also the dedication to accomplish difficult tasks
  718. under adverse circumstances. Wouldn‘t survival of catastrophic change make a sound national or
  719. global objective?
  720.  
  721. The apparent prerequisite for polar shift is the movement of the magnetic pole toward the geographic
  722. pole. and according to the U . S. Geological Survey, this prerequisite is being met. From 1831 until
  723. 1945, the magnetic north pole remained almost static on Boothia Peninsula in the Northwest
  724. Territory of Canada. moving only 24 miles in 114 years. However, in 1947, Frank Klein‘s plottings
  725. revealed that the magnetic pole had begun a dramatic northward progression. All told, from 1945
  726. to 1992, the magnetic pole has moved 468 miles northward toward the geographic pole with an
  727. average closure rate of approximately 10 miles per year. Today, only 700 miles separate the two
  728. poles.'0 Until further research is conducted, exactly when the break and rapid acceleration of the
  729. magnetic pole toward the geograch pole will occur is unknown.
  730.  
  731. unded when, in the
  732. early 19505, information about the flip phenomenon was released in both a newspaper column and
  733. a magazine article, but surprisingly generated no responses from an apparently stunned, parochial
  734. or incredulous public. It would seem that today’s society, however, with its access to vast amounts
  735. of information and technological capability, should be better equipped to offer the sophisticated,
  736. profuse and innovative reactions that the situation would seem to require.
  737.  
  738. Only by making the facts known can we begin to mobilize the resources and brainpower necessary
  739. to overcome the obstacles. Clearly. a society that can deal responsibly with the concept of
  740. catastrophic change has the best chance of preparing for and surviving the change itself. What we
  741. do to prepare for the upcoming polar flip and its aftemiath will amount to nothing less than a
  742. safeguard against total disaster. The difference between human beings and other creatures is that our
  743. destiny is not carved in stone. With purpose, ingenuity and fortitude, we can change it if we so
  744. endeavor.
  745.  
  746. Of possible interest is the curious choice of words of the early psalmists:
  747.  
  748. God is our refuge and strength,
  749.  
  750. A very present help in trouble.
  751. Therefore we will not fear,
  752.  
  753. Though the earth should change,
  754. And though the mountains
  755.  
  756. slip into the heart of the sea;
  757. Though its waters roar and foam,
  758. Though the mountains quake
  759.  
  760. at its swelling pride.
  761.  
  762. (Psalm 46, W. 1-4)
  763.  
  764. Bless the Lord, 0 my soul!...
  765.  
  766. ...He established the earth
  767. upon its foundations,
  768. So that it will not totter
  769. forever and ever.
  770. Thou didst cover it with
  771. the deep as with a garment;
  772. The waters were standing
  773.  
  774. above the mountains.
  775. At Thy rebuke they fled;
  776.  
  777. 198
  778.  
  779. World in Peril
  780.  
  781. At the sound of Thy thunder
  782. they hurried away.
  783. The mountains rose;
  784. the valleys sank down
  785. To the place which Thou
  786. established for them.
  787. Thou didst set a boundary
  788. that they may not pass over;
  789. That they may not return
  790. to cover the earth...
  791.  
  792. ...Let the glory of the Lord
  793. endure forever;
  794.  
  795. Let the Lord be glad in
  796. His works.
  797.  
  798. He looks at the earth,
  799. and it trembles;
  800.  
  801. He touches the mountains,
  802. and they smoke.
  803.  
  804. I will sing to the Lord as
  805. long as I live;
  806.  
  807. I will sing praise to my
  808. God while I have my
  809. being...
  810.  
  811. (Psalm 104, W. 5-9, 31-33)
