Avalanche Canyon

Avalanche Canyon is a valley in Grand Teton National Park that lies between South Teton and Mount Wister. The terrain features rocky slopes and several alpine lakes along with a waterfall in the upper section.

Ice age glaciers carved this valley into its U-shaped form roughly 15,000 years ago during the last glacial period. The erosional forces created the steep rock walls and deep terrain features visible today.

Indigenous populations inhabited the surrounding territories before the establishment of Grand Teton National Park in 1929, maintaining strong land connections.

Hikers should have moderate fitness and comfort navigating mountain terrain, particularly on steeper sections. The best time to explore is from June through September when snow has melted and trails are passable.

The canyon contains three distinct water features at its head: Snowdrift Lake, Lake Taminah, and Shoshoko Falls, forming a natural water system.
