Capitol Reef National Park lies near Torrey, Utah. It includes a ridge that is topped by a white sandstone formation that resembles a capitol dome. The park also includes the Waterpocket Fold. This feature, 100 miles (160 kilometers) long, is a fold in Earth’s crust with shallow depressions that collect and hold water. The area was set up as a national monument in 1937 and became a national park in 1971. For area, see National Park System (table: National parks).
