Mount Lyell is located on the Great Divide, which forms the BC-Alberta boundary in this area, in Banff National Park. Collectively, the five peaks, and the Mt. Lyell massif itself, are commonly referred to as 'the Lyells'.[3] The mountain is the highest in the Lyell Group, a subrange of the Central Icefields in the Canadian Rockies.[6]
In 1972, five distinct peaks on Mt. Lyell (formerly referred to as only Lyell 1 through 5 or L1 through L5), were named after Swiss mountain guides who settled in Golden, British Columbia in 1912. Running south to north along the interprovincial boundary, these peaks are: Christian Peak (L5), Walter Peak (L4), and Ernest Peak (L3), named after Christian Hässler, Walter Feuz and Ernest Feuz. Located entirely in Alberta are Edward Peak (L2) and Rudolph Peak (L1), named after Edward Feuz Jr. and Rudolph Aemmer.[4]
Mount Lyell marks the limit between the South Saskatchewan and Columbia watersheds.
Mount Lyell is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[7] The Lyell Formation is named after Mount Lyell.[8] Geology for all five subpeaks is identical due to their proximity to the central peak (maximum distance: 1.6 km or 1 mile).
Based on the Köppen climate classification, Mount Lyell is located in a subarctic climate with cold, snowy winters, and mild summers.[9] Temperatures can drop below −20 °C (−4 °F) with wind chill factors below −30 °C (−22 °F).
