Maligne Lake, Jasper National Park

Maligne Lake is the largest lake in Jasper National Park. The valley in which the lake lies was carved and excavated by valley glaciers, and the lake has been dammed at its northern end by an end moraine deposited by the last glacier. It is famed for the color of its water, the surrounding peaks, the three glaciers visible from the lake and Spirit Island, a frequently photographed islet.

At the northern end of the lake, the river flows out of the lake in a narrow channel to Medicine Lake. There is no visible northern outlet from Medicine Lake because the Maligne River flows underground (except during flood) for 9 miles before reappearing in its remarkable canyon (see August 11, 2017 on this web site), which is about 180 feet in depth.
