The Old Woman River
is a river
in the Algoma District
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.
