The peak was named in 1892 after the Stoney Indian word "Sunwapta" meaning "turbulent river". The mountain can be seen from the Icefields Parkway (Highway 93). RoutesThe normal climbing route is via the southwest slopes, requiring an elevation gain of {{convert|1735|m|ft|0|abbr=on}} to the summit from the trail head located beside the Icefields Parkway. GeologySunwapta Peak is composed of sedimentary rock laid down from the Precambrian to Jurassic periods that was pushed east and over the top of younger rock during the Laramide orogeny.[2] ClimateBased on the Köppen climate classification, Sunwapta Peak is located in a subarctic climate with cold, snowy winters, and mild summers.[3] Temperatures can drop below -20°C with wind chill factors below -30°C. Precipitation runoff from Sunwapta Peak drains into the Sunwapta River which is a tributary of the Athabasca River.
