Old Man's Creek flows in a broad valley cut into the soft sandstones of the Logan Formation. Here the stream flows across a wide flat area of resistant bedrock, which marks the position of the Berne conglomerate and then begins a steep plunge over a series of small waterfalls. This cascade terminates in the waterfall known as the Upper Falls. Bedrock is from the Mississippian Geologic Period. The photograph was taken by George W. White in 1945.
