Precambrian Glaciated Surface Beneath the Gowganda Formation, Lake Timagami, Ontario.
Glacial deposition of the Gowganda formation is established by the discovery of an extensive, well-marked, glaciated, basal contact surface. This surface is exposed near the southeastern end of Lake Timagami, northern Ontario. The Precambrian ice sheet advanced three times from the northeast over the area.
