Based on the Köppen climate classification, it is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.{{cite journal | author = Peel, M. C. |author2=Finlayson, B. L. |author3=McMahon, T. A. | year = 2007 | title = Updated world map of the Köppen−Geiger climate classification | journal = Hydrol. Earth Syst. Sci. | volume = 11 | pages = 1633–1644 | issn = 1027-5606}} Temperatures can drop below −10 °F with wind chill factors below −30 °F.

Geology

Like other mountains in Glacier National Park, it is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks {{convert|3|mi|km|1|abbr=on}} thick, {{convert|50|mi|km}} wide and {{convert|160|mi|km}} long over younger rock of the cretaceous period.{{cite journal|title=Geology of the Rocky Mountains and Columbias |author=Gadd, Ben |year=2008}}
