Mahtotopa Mountain

Mahtotopa Mountain (8,677 feet (2,645 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.[3] Mahtotopa Mountain rises to the south above Saint Mary Lake midway between Red Eagle Mountain and Little Chief Mountain and can be easily seen from the Going-to-the-Sun Road to the southwest of Rising Sun. Originally named Four Bears Mountain by George Bird Grinnell in 1885, the name was changed in 1932 to Mahtotopa. Mahtotopa is an incorrect spelling of "Mato-tope", the Mandan chief known as Four Bears. Mato-tope was a grandfather of Joe Kipp, a hunting companion of Grinnell.

Climate

Geology

Like other mountains in Glacier National Park, Mahtotopa 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 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.[5]
