Falls of the Ohio River

A world-famous fossil locality, the Falls of the Ohio is comprised of a ledge of Devonian limestone (Jeffersonville Limestone) that protrudes out of the river channel and is surrounded by gravels deposited during the Pleistocene. This is where William Clark met with the growing Corps of Discovery in October 1803. (Lewis and Clark, 8/25/1803)
