Death Valley National Park
Natural Bridge is a stunning geologic formation tucked back in a Death Valley canyon.
The bridge rises approximately 35 ft (11 m) above the canyon floor and is about 35 ft (11 m) thick. Although rain is infrequent in Death Valley, over thousands of years, flash flood events have carved the canyon which Natural Bridge spans today. At some point, the water changed course slightly and ran just north of the present location of the bridge (look for this diversion as you hike). This diversion lowered the level of the canyon just above the location of the bridge. Eventually, the water returned to its initial, straighter course, forming a hole under the span of the bridge and eventually lowering the floor of the canyon even more, creating the bridge and leaving it high and exposed.
