Yellowstone Natural Bridge is a natural arch in Yellowstone National Park, Wyoming. The arch is at an elevation of 7,983 feet (2,433 m) and can be reached by hiking a little more than a mile from the Bridge Bay marina parking lot.[1][2] The arch is 51 feet (16 m) tall and was created as water eroded through the surrounding rhyolite rock.[3]
