Lake Agassiz

During the height of the last ice age, technically known as the Pleistocene, Manitoba was almost entirely covered by an enormous glacier. The warmer climates, which marked the end of the ice ages, led to the formation of Lake Agassiz from the glacial meltwaters. This lake was to cover a major part of the province between 10,000 and 6,000 B.C.

The depth of the now extinct lake is revealed by a number of old shorelines, such as the Campbell beach (below) formed in Western Manitoba after 8,000 B.C.
