Silver Cord Cascade
Silver Cord Cascade is a horsetail type waterfall on Surface Creek, a tributary of the Yellowstone River in Yellowstone National Park. 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.
Cumberland Falls
On average the falls, which flows over a resistant sandstone bed, is 68 feet (21 m) high and 125 feet (38 m) wide. Cumberland Falls is the second largest waterfall east of the Rocky Mountains, and the largest waterfall as measured by water volume in the Eastern United States, south of Niagara Falls. The falls divides the river into two sections, the Upper and Lower, or "below the falls" section.
