Access to the Gypsum Sinkhole requires a high clearance vehicle. Call 435-425-3791, press 1 for more information, and 4 for road conditions before visiting. Visit the Cathedral Valley page for more information and check the forecast. The roads through Cathedral Valley can become impassable when wet. 

Stay away from the edge of the Gypsum Sinkhole. The rocks here are very soft and unstable, and can collapse at any time.

Geology

The Gypsum Sinkhole was formed when groundwater dissolved a buried gypsum plug. The cavity left behind has collapsed under the weight of overlying rock layers. This collapse has created a large sinkhole nearly 50 feet (15 m) in diameter and 200 feet (61 m) deep.

Gypsum is a common mineral found in the sedimentary rocks of this area. According to the Utah Geological Survey, "the gypsum was deposited from evaporating seawater approximately 165 million years ago (upper part of the Middle Jurassic Carmel Formation). After deposition and burial under subsequent layers of sediment, the low-density gypsum moved slowly upward along faults or fractures."
