Matahpi Peak

Matahpi Peak (9370 ft) is located in the Lewis Range, 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 1 mi 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 3 mi thick, 50 mi wide and 160 mi long over younger rock of the cretaceous period.
