Moaning/Towns

Still, these aspects of the ecosystem did not really concern any of us. Other elements had the ability to unsettle, however. Long ago, towns had existed here, and we encountered eerie signs of human habitation: rotting cabins with sunken, red-tinged roofs, rusted wagon-wheel spokes half-buried in the dirt, and the barely seen outlines of what used to be enclosures for livestock, now mere ornament for layers of pine-needle loam.
Far worse, though, was a low, powerful moaning at dusk. The wind off the sea and the odd interior stillness dulled our ability to gauge direction, so that the sound seemed to infiltrate the black water that soaked the cypress trees. This water was so dark we could see our faces in it, and it never stirred, set like glass, reflecting the beards of gray moss that smothered the cypress trees. If you looked out through these areas, toward the ocean, all you saw was the black water, the gray of the cypress trunks, and the constant, motionless rain of moss flowing down. All you heard was the low moaning. The effect of this cannot be understood without being there. The beauty of it cannot be understood, either, and when you see beauty in desolation it changes something inside you. Desolation tries to colonize you.
