Chapman Peak

Chapman Peak (9411 ft) is located in the Livingston Range, Glacier National Park in the U.S. state of Montana. Chapman Peak is situated along the Continental Divide. The mountain is named for Robert H. Chapman, one of the US Geological Survey topographers who worked on mapping Glacier Park between 1900 and 1904.

Climate
Based on the Köppen climate classification, Chapman Peak is located in a subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers. Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.

Geology
Like other mountains in Glacier National Park, Chapman Peak 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 3 mi thick, 50 mi wide and 160 mi long over younger rock of the cretaceous period.
