Roche Bonhomme is a 2,495-metre (8,186-foot) mountain summit located in Jasper National Park in Alberta, Canada. It is located in the Colin Range, which is a sub-range of the Canadian Rockies.[5][4] The peak is situated 13 km (8.1 mi) northeast of the municipality of Jasper, and is a prominent landmark in the Athabasca Valley visible from Highway 16 and the Canadian. Its nearest higher peak is Grisette Mountain, 2.2 km (1.4 mi) to the east.[3]
Roche Bonhomme was named in 1878 by George Munro Grant for the fact it has an anthropomorphic shape.[6] The French "Roche Bonhomme" translates to "Rock Fellow." The mountain's name was officially adopted in 1947 by the Geographical Names Board of Canada.[4] Roche Bonhomme is composed of Permian and Carboniferous strata topped by darker Triassic siltstone of the Sulphur Mountain Formation.[7]
Based on the Köppen climate classification, Roche Bonhomme is located in a subarctic climate with cold, snowy winters, and mild summers.[8] Temperatures can drop below -20 °C with wind chill factors below -30 °C. In terms of favorable weather, June through September are the best months to climb. Precipitation runoff from Roche Bonhomme flows into tributaries of the Maligne River which in turn is a tributary of the Athabasca River.
