Chak Peak is a 2,775-metre summit in Jasper National Park’s Athabasca River valley in Alberta’s Canadian Rockies. Its name comes from the Stoney language, meaning “eagle,” and reflects an Indigenous place-naming tradition in the region. The mountain’s runoff flows into Portal Creek and the Astoria River, both part of the Athabasca watershed. Chak Peak lies in a subarctic climate with cold, snowy winters, mild summers, and severe winter wind chill. Geologically, it is composed of sedimentary rock deposited from the Precambrian to the Jurassic, then thrust eastward over younger layers during the Laramide orogeny that helped form much of the Rockies.
