Little Matterhorn is a 7,886-foot (2,404 meter) elevation mountain summit located in the Lewis Range, of Glacier National Park in the U.S. state of Montana.

[3] The nearest higher peak is Edwards Mountain, 0.9 miles (1.4 km) to the south.

[1] Precipitation runoff from the mountain drains into creeks which empty into Lake McDonald.

Like other mountains in Glacier National Park, Little Matterhorn 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.
