Capitol Reef National Park is a U.S. National Park, in south-central Utah. It is 100 miles long. The park, established in 1971, preserves 378 mi² of colorful canyons, ridges, buttes, and monoliths and the long Waterpocket Fold up-thrust. Capitol Reef is the name of an especially rugged and spectacular part of the Waterpocket Fold near the Fremont River. The area was named for a line of white domes and cliffs of Navajo Sandstone, each of which looks somewhat like the United States Capitol building, that run from the Fremont River to Pleasant Creek on the Waterpocket Fold. The local word reef referred to any rocky barrier to travel.
