Silver Cord Cascade

Surface Creek flows out of Ribbon Lake off the South rim of the Grand Canyon of the Yellowstone and plunges to the Yellowstone River. It is considered the tallest waterfall in Yellowstone.
Hetch Hetchy
Wapama Falls, at , and Tueeulala Falls, at – both among the tallest waterfalls in North America – are both located in Hetch Hetchy Valley. Rancheria Falls is located farther southeast, on Rancheria Creek. Formerly, a "small but noisy" waterfall and natural pool existed on the Tuolumne River marked the upper entrance to Hetch Hetchy Valley, informally known as Tuolumne Fall (not to be confused with a similarly named waterfall several miles upriver near Tuolumne Meadows). The waterfall on the Tuolumne is now submerged under Hetch Hetchy Reservoir.
