Ribbon Cascade, Waterfall in Grand Teton National Park, Wyoming, United States

Ribbon Cascade is a waterfall in Hanging Canyon in Grand Teton National Park, Wyoming, dropping about 600 feet (180 m) near the canyon's eastern end, west of Jenny Lake and east of Symmetry Spire and Mount Saint John. It falls in a thin ribbon fed by an unnamed intermittent stream that drains the Lake of the Crags, Ramshead Lake and Arrowhead Pool.

Ribbon Cascade lies in Hanging Canyon, east of Symmetry Spire and Mount Saint John in the Teton Range, and drains the chain of Arrowhead Pool, Ramshead Lake and Lake of the Crags toward Jenny Lake. Its 107-metre (about 600-foot) drop is fed by an unnamed intermittent stream whose flow peaks with spring snowmelt, yet the cascade is rarely dry because it is the only outlet for those upper lakes.

The waterfall is visible from the east side of Jenny Lake, especially when the water is flowing strongly in spring. There are no marked trails leading directly to it, so the terrain around the canyon is uneven and requires solid preparation.

The cascade is fed by a hidden stream system that connects the Lake of the Crags, Ramshead Lake, and Arrowhead Pool high above in the mountains. Without this chain of linked water bodies, the waterfall would barely flow outside of snowmelt season.
