- Description
- The geologic map of the Canyon Ferry Dam 30' x 60' quadrangle, west-central Montana, portrays the geology of an area of about 4,200 km2 , extending from near the capital city of Helena east about 74 km and about 55 km from south to north. The area encompasses the scenic canyons of the Missouri River through the Gates of the Rocky Mountains and the Smith River through the west end of the Little Belt Mountains, and includes the eastern part of Helena Valley, the northern end of the Townsend Valley, and the Smith River Valley. The quadrangle lies at the junction of four major tectonic elements: the Montana disturbed belt, the Lewis and Clark tectonic zone, the Boulder batholith and associated intrusive bodies, and the continental autochthon.
