Site Formation
Fell's Cave is located in the Río Chico canyon, Chile, near the Straits of Magellan and the Argentine border. This area is known as the southeastern Patagonian basalt plateaus. Situated on the southeast side of what was once a river bank, it is more accurately described as a shelter. It was formed by river water wearing away at the sandstone bank, leaving behind a canopy of lava conglomerate and thus creating a shelter 28 feet deep and 38 feet wide. The erosion formed a smooth floor of hard clay. Remnants of sandstone still clinging to the conglomerate roof eventually fell to the floor, forming a sterile layer that later separated human occupation periods.

Famous quotes containing the words site and/or formation:
“I am not aware that any man has ever built on the spot which I occupy. Deliver me from a city built on the site of a more ancient city, whose materials are ruins, whose gardens cemeteries. The soil is blanched and accursed there, and before that becomes necessary the earth itself will be destroyed.”
—Henry David Thoreau (1817–1862)
“It is because the body is a machine that education is possible. Education is the formation of habits, a superinducing of an artificial organisation upon the natural organisation of the body.”
—Thomas Henry Huxley (1825–1895)
