Mount Helen (8,538 feet (2,602 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.[3] Mount Helen rises immediately to the northwest roughly 3,100 feet (940 m) above Upper Two Medicine Lake in the southeastern part of Glacier National Park.[4] The Continental Divide of the Americas passes over the summit of Mount Helen.
Like the mountains in Glacier National Park, Mt. Helen 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]
