The Black River Escarpment is a geological feature in southeastern Ontario.[1][2] An escarpment is a long, steep slope, especially one at the edge of a plateau or separating areas of land at different heights. The Black River escarpment marks the boundary of the older Canadian Shield bedrock and more recent Ordovician limestone. The escarpment runs from Penetanguishene on Georgian Bay to Kingston on Lake Ontario. The cliffs that mark the escarpment, when present, generally average between 5 m (16.4 ft) and 15 m (49.21 ft) high.
