Called "Wayne Wonderland" in the 1920s, Capitol Reef National Park comprises 378 square miles of colorful canyons, ridges, buttes, and monoliths. About 75 miles of the long up-thrust called the Waterpocket Fold, extending like a rugged spine from Thousand Lake Plateau southward to Lake Powell, is preserved within the park boundary.

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, like a coral reef.
