Yellowstone Canyon

The Grand Canyon of the Yellowstone River is a 24-mile long, 800 to 1,200 feet deep, and 0.25 to 0.75 miles wide canyon located in Yellowstone National Park, Wyoming. The canyon was formed by erosion as the Yellowstone River flowed over progressively softer, less resistant rock. Visitors can experience the canyon from a variety of overlooks, at different times of day, and at different seasons. A number of trails and walkways wind along the rims and down partway into the canyon, including the Brink of the Lower Falls Trail and the Red Rock Points Trail. The canyon is also home to a variety of wildlife, including osprey, which can be seen soaring over the river or perched on their nests. The canyon's multi-hued rocks result from hydrothermally altered rhyolite and sediments, and visitors can see still-active hydrothermal features near the river
