The mountain forms a cirque, hence the name.[3] Scrambling RouteThe scrambling route (rated easy) begins just beyond Helen Lake which can be reached by following the Helen Lake/Dolomite Pass trail 6 km from the trail head beside the Icefields Parkway. From the lake, follow the trail into Dolomite Pass and then choose a line up the peak.[4] GeologyLike other mountains in Banff Park, Cirque Peak is composed of sedimentary rock laid down during the Precambrian to Jurassic periods.[5] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[6] ClimateBased on the Köppen climate classification, Cirque Peak is located in a subarctic climate with cold, snowy winters, and mild summers.[7] Temperatures can drop below −20 °C with wind chill factors below −30 °C.
