Niagara Escarpment

The Niagara Escarpment (english Niagara Escarpment ) is an elongated Escarpment in the U.S. and Canada. It runs from the New York State across Ontario, Michigan and Wisconsin to Illinois. The hilly terrain is made of hard dolomite rock at the surface, below it a layer of soft shale. The Escarpment is named after the Niagara Falls. In February 1990, it was declared a UNESCO Biosphere Reserve.

The Niagara Escarpment is the most prominent of several escarpments that have formed during the Silurian in the basement in the Great Lakes region. It starts east of the valley of the Genesee River in Rochester and continues on Niagara River, where it forms north of Niagara Falls, a deep gorge. In southern Ontario it runs close to Lake Ontario via the Niagara Peninsula, then right through the city of Hamilton and then turns north to Georgian Bay. She follows in the northwest to the shores of Lake Huron, forming the back of the Bruce Peninsula, Manitoulin Island and other islands. Subsequently, the Escarpment is westward to the Upper Peninsula of northern Michigan continues, turns to the southwest, follows the Door Peninsula and the western shore of Lake Michigan and eventually ends north of Chicago.
