Leah Peak is a 2,801-metre (9,190 ft) mountain summit located on the eastern shore of Maligne Lake in Jasper National Park, in the Canadian Rockies of Alberta, Canada.

[2] Leah Peak was named by Mary Schäffer in her expedition through the area in 1908 to find Maligne Lake.

Samson was a Stoney Indian who befriended Mary and provided her with a hand drawn map to assist her with finding the way to the elusive lake.

Samson visited the lake with his father at the age of 14, and 16 years later he drew the map from memory when he met Mary at Elliott Barnes' cabin on the Kootenay Plains in the Saskatchewan Valley.

[3] Based on the Köppen climate classification, Leah Peak is located in a subarctic climate with cold, snowy winters, and mild summers.
