Silver Cord Cascade, Multi-tier waterfall in Yellowstone National Park, United States

Silver Cord Cascade is a horsetail waterfall on Surface Creek, which drains Ribbon Lake off the south rim of the Grand Canyon of the Yellowstone. The creek plunges about 1,200 feet (370 m) to the Yellowstone River, making it the tallest waterfall in the park.

The waterfall was first documented by the Washburn-Langford-Doane Expedition in 1870 under the name Silverthread Falls. The current name was officially adopted in 1885.

The name reflects how water appears to cascade down in silver-like strands across the rock face. Visitors often notice this shimmering quality when sunlight hits the falling water throughout the day.

The brink of Silver Cord Cascade is reached via the Clear Lake–Ribbon Lake trail. To see the falls themselves, take the Sevenmile Hole trail along the North rim of the Grand Canyon of the Yellowstone. Surface Creek leaves Ribbon Lake on the South rim and drops 1,200 feet (370 m) to the Yellowstone River.

At 1,200 feet (370 m), Silver Cord Cascade is considered the tallest waterfall in Yellowstone, dropping from the south rim of the Grand Canyon of the Yellowstone into the river below. Its brink is reached by the Clear Lake–Ribbon Lake trail, but the falls themselves are seen from the North Rim via the Sevenmile Hole trail.
