Olson Mountain,[4] also known as Mount Olson, is a 7,913-foot-elevation (2,412 m) mountain summit located in the Livingston Range, of Glacier National Park in the U.S. state of Montana. Olson Mountain rises more than 3700feet above the western shore of Waterton Lake. The mountain was named for a surveyor on the International Boundary Survey, with the name officially adopted in 1929.[4] The nearest higher peak is Campbell Mountain, 1.13miles to the north, and Citadel Peaks is two miles (3.2 km) to the south.[1] Precipitation runoff from the mountain drains into Olson Creek before it empties to Waterton Lake.
Based on the Köppen climate classification, Olson Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers.[5] Temperatures can drop below −10°F with wind chill factors below −30°F.
Like other mountains in Glacier National Park, Olson Mountain 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 31NaN1 thick, 50miles wide and 160miles long over younger rock of the cretaceous period.[6]
