[1] The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago.

[2] Cascade Creek now flows where the glaciers once did and the numerous waterfalls, such as the 100-foot (30 m) tall Hidden Falls, found within the gorge are popular destinations with tourists.

From there, hikers have the option of heading north along the Lake Solitude Trail to Lake Solitude (another 2.8 miles (4.5 km) or south via the South Fork Cascade Canyon Trail to Hurricane Pass (5.1 miles (8.2 km).

Steep cliffs descending from these peaks ensure that the high points to the north and south are not visible until one hikes considerable distance into the canyon.

Five miles (8 km) west of Jenny Lake the Cascade Canyon Barn is preserved.
