Wikipedia describes the map above:
"The Niagara Escarpment is the most prominent of several escarpments formed in the bedrock of the Great Lakes. It is traceable from its easternmost point in New York State, starting well east of the Genesee River Valley near Rochester, creating one large and two small waterfalls on the Genesee River in that city, thence running westwards to the Niagara River forming a deep gorge north of Niagara Falls, which itself cascades over the escarpment. In Southern Ontario it stretches along the Niagara Peninsula hugging close to the Lake Ontario shore near the cities of St. Catharines and Hamilton and Milton where it takes a sharp turn north toward Georgian Bay. It then follows the Georgian Bay shore northwestwards to form the spine of the Bruce Peninsula, Manitoulin, St. Joseph Island and other islands located in northern Lake Huron where it turns westerwards into the Upper Peninsula of northern Michigan, south of Sault Ste. Marie. It then extends southwards into Wisconsin following the Door Peninsula and then more inland from the western coast of Lake Michigan and Milwaukee ending northwest of Chicago near the Wisconsin-Illinois border."
West of Toronto is Mount Nemo Conservation Park, a part of the Bruce Trail System on the Niagara Escarpment.
 Mount Nemo is an elbow in the Niagara Escarpment north of the City of Burlington, Ontario. The limestone cliff edge, fractured with crevice caves, is covered with an old cedar forest. Part of the Bruce Trail, it is a popular location for hiking and... surprise surprise... rock climbing. Although I have more of a spectator view of rock climbing, my bones are becoming too old for this sport, thus I leave it to the more adventerous. It is enough that I can walk portions of the trail.
Mount Nemo Conservation Area is operated by Conservation Halton. It has five kilometers of hiking trails that connect with the Bruce Trail.
