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 3,700 feet (1,100 m) above the western shore of Waterton Lake.

[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.

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 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.
