Grandfather's grandfather saw Thunder. He went out to hunt in a great rain. After the rain, they rode to a high point on the mountain and there saw a great eagle grey like a pigeon with red stripes over the eye and along the wing. The head was drooped down and was big like a man's head; the bill and claws and wings were like an eagle. He sat about four feet high. They offered the eagle tobacco, hair and skin. That night there was constant thunder and lightning and in the morning (all was clear). One of the eagle's wings hung down as if broken. There was a big lake with lots of fish and a big turtle so big that six men could hold hands about its body. Big fish lay thrown out about the pond and smelled bad. A big black animal was dead there also. This (eagle) was Waki'ya.
