The San Rafael Reef, a 30 mile barrier at the edge of nowhere, the eastern margin of the San Rafael Swell. John Wesley Powell described the swell as "a land of desolation, dedicated forever to the geologist and artist, where civilization can find no resting place". The swell is a huge dome-shaped anticline of sedimentary rock that formed during the Laramide Orogeny about 60-40 million years ago.
