Close Encounter of the Niagria Escapment
Bayshore County Park, Wisconsin. The Niagara Escarpment is a prominent rock ridge that spans nearly 1,000 miles in an arc across the Great Lakes region, forming the ancient “backbone” of North America. It runs from eastern Wisconsin to the Upper Peninsula of Michigan, through southern Ontario to western New York State, where Niagara Falls cascades over it, giving the escarpment its name. The red line on this map shows the path of the Niagara Escarpment.
