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.
Annie Falls
Annie Falls, is the tallest of three waterfalls so named, located along Annie Creek in the Crater Lake National Park at the south end of Rim Village Historic District, in Klamath County, in the U.S. state of Oregon. It is located in a steep canyon area surrounded by walls of petrified volcanic ash as a consequence of the Mount Mazama eruption. The location of Annie Creek Falls deep in the Annie Creek canyon makes it very difficult to reach the waterfall. Partial views of the cascade can be seen from a picnic area off the Volcanic Legacy Scenic Byway south of Crater Peak. Access to Annie Creek is available at the USFS snow park, both the creek and the waterfall possess a high water flow.
