Avalanche Canyon, Canyon in Grand Teton National Park, Wyoming, United States.

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.

The name Avalanche Canyon refers to snowslides that sweep its slopes; the Teton Range's glaciers left the U-shaped trough hikers walk today. Shoshoko Falls, about 1.5 km west of the canyon, and Bannock Falls, roughly 2 km northeast, are the nearby landmarks. The village of Moose lies about 8 km to the southeast.

Avalanche Canyon has no road access; the approach is a hike of roughly 6 miles round trip from the trailhead, and the route crosses steep mountain terrain. Snow can linger on upper sections into early summer, so check conditions before setting out. Shoshoko Falls lies about 1.5 km west of the canyon and Bannock Falls about 2 km northeast.

Shoshoko Falls sits about 1.5 km west of the canyon, while Bannock Falls lies roughly 2 km to the northeast. The village of Moose is about 8 km southeast. Shadow Peak and Nez Perce Peak stand on the Teton Range.
