Slippery Rock Gorge

Slippery Rock Creek - McConnells Mill According to the DCNR Website, 140,000 years ago there was a lake to the north of Cleland Rock whose waters were bound by the edge of a continental glacier. As the glacier receded, the ice dam burst and the ensuing torrent of water carved the already existing valley 400 feet deeper. The change was so drastic that streams which normally flowed north changed direction and now flow south. It is hard to imagine such power.

  1. This reminds me of what they think happened in Montana, that a burst galcier carved out a whole plain and that it happened very suddenly and very quickly. It is amazing.
