Cave Point Karst
December 30, 2009
The above photo was taken from a ledge on the Lake Michigan shoreline at Cave Point County Park on the east coast of Wisconsin’s Door Peninsula. The peninsula is a part of the Niagara Escarpment which stretches in a huge arc from Wisconsin, over Michigan's Lower Peninsula, and down the Canadian province of Ontario to Niagara Falls. The rock ledge is a karst formation consisting of Silurian Period dolomite which is often mistaken for limestone. The lake waves and currents have worn away the rock and created the bluffs and caves. Photo taken October 8, 2008.
