Anatomy of an overthrust fault. The Lewis Overthrust is a geologic thrust fault structure of the Rocky Mountains found within the bordering national parks of Glacier in Montana, United States and Waterton Lakes in Alberta, Canada. The fracturing that gave rise to the Lewis overthrust began several miles below the surface and probably a long way west of the site of Glacier National Park, where the hard but brittle Belt rocks broke.
