Lake Stanley
Lake Stanley, also called the Stanley unconformity, is a postglacial freshwater lake that occupied part of what is now the basin of Lake Huron during a hydrologically significant period from 10,000 years Before Present (B.P.). The lake’s surface level was approximately 70 meters below the current lake’s water surface.

The lake, although geographically smaller than the current Lake Huron, was fed from a large Lake Chippewa watershed that included the basin of what is now Lake Michigan. During this period, the water from Lake Stanley drained through an outlet or outlets adjacent to what is now North Bay, Ontario.
