Matahpi Peak

Matahpi Peak is located in the Lewis Range, Glacier [National Park (US)|Glacier National Park] in the U.S. state of Montana. Below the summit of Matahpi Peak lies Sexton Glacier. Going-to-the-Sun Mountain is just over to the south of Matahpi Peak.

Geology

Like other mountains in Glacier National Park, Matahpi 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 thick, wide and long over younger rock of the cretaceous period.
