Cascade Canyon, Grand Teton National Park

Cascade Canyon is located in Grand Teton National Park, in the U.S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago. Today, Cascade Canyon has numerous polished glacial erratics, hanging cirques and a U-shape as evidences that demonstrate that glaciers once filled the canyon to a depth of at least 2,000 feet. Rock debris that was transported out of the canyon by glacial motion formed moraines which now impound the waters of Jenny Lake which is located at the base of the canyon. Cascade Creek now flows where the glaciers once did and the numerous waterfalls, such as the 100-foot tall Hidden Falls, found within the gorge are popular destinations with tourists. ()
