Mount Cannon () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Formerly called Goat Mountain it was renamed for the leading physiologist Dr. Walter Bradford Cannon and his wife Cornelia, who made the first recorded ascent of the mountain in 1901. Geology Like other mountains in Glacier National Park, Cannon 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 thick, wide and long over younger rock of the cretaceous period. Climate Based on the Köppen climate classification, Cannon is located in a subarctic climate characterized by long, usually very cold winters, and short, cool to mild summers. Temperatures can drop below −10 °F with wind chill factors below −30 °F.
