The Lewis Range of the Rocky Mountains was formed 170 million years ago as a result of an overthrust when colliding tectonic plates shoved a huge rock slab, half a dozen kilometers thick, eastward more than 100 kilometers. The peaks were then sculpted by glaciation. This range reaches a height of over 3, 000 meters and forms the eastern edge of the Rockies along the Montana-Alberta border. It extends from Glacier to Waterton Lakes National Parks. | |
