Open Canyon

Open Canyon in Wyoming’s Grand Teton National Park is a glacially carved, U-shaped valley formed when ice retreated from the Teton Range at the end of the Last Glacial Maximum about 15,000 years ago. Lying between Mount Hunt and Prospectors Mountain with Coyote Lake at its head, it reflects the region’s glacial past rather than erosion by a river. Reached by the Open Canyon Trail, it remains one of the park’s quieter mountain canyons and is notable for the especially clear way its terrain preserves the imprint of Ice Age geology.
