Old Woman River (Ontario)

The Old Woman River is a river in the Algoma District of Ontario, Canada which empties into Old Woman Bay on Lake Superior south of Wawa, Ontario. It flows through Lake Superior Provincial Park.

The river follows a fault which became a spillway for glacial meltwater following the last ice age.

Towering cliffs along the bay have been home to peregrine falcons.

The name for the bay and river come from a rock formation near the river's mouth that resembles the face of an old woman. The river's mouth is located at 47.789743°N 84.895672°W / 47.789743; -84.895672
