Medicine Lake: The name originates from the Cree, indicating ceremonial or religious aspects of tribal visits to the area. Medicine Lake is renowned for its underground river system. In spring and summer the capacity of the sink holes (bottom of lake) is exceeded and the lake level rises. By late summer the sink holes drain more water than the lake gets and the level drops dramatically.
Maligne Lake: Maligne (mah-leen) is the French word for "wicked". It was given to the river after a difficult crossing by Jesuit missionary Pierre Jean deSmet. The lake is by far the largest natural lake in the Rockies, with its 22 km. You can access the far end by boat (fee) or walk around.
Maligne Canyon: The canyon was created by the erosion of the bedrock. It is the longest, deepest and most interesting limestone canyon in the Rockies.
