The Niagara Escarpment

The Niagara Escarpment

What do Lake Winnebago and Niagara Falls have in common? The Niagara Escarpment. This is a big bedrock ledge formed through erosion that forms the Door Peninsula as well at the Bruce Peninsula (in Canada) and Niagara Falls (see the map on the link). It also makes digging difficult in the western parts of my district since the bedrock is so close to the surface (from an Eagle project). The only reason I looked this up was that I was hiking Sunday at High Cliff State Park just outside of Appleton on the north end of Lake Winnebago and wondered why there was a cliff there. It's a steep hike from the cliff bottom to the top where the camping area is, but it provides a great view of the lake (see photo posted after this post). I would never have guessed that there was a cliff like that in central Wisconsin. Now I know why.
