Capitol Dome is a 6,120-foot-elevation (1,870 m) summit located in Capitol Reef National Park, in Wayne County, Utah, United States. This iconic landmark is situated 2.5 miles (4.0 km) east of the park's visitor center, and 0.85 mi (1.37 km) southeast of Navajo Dome. Precipitation runoff from this feature is drained by tributaries of the Fremont River, which in turn is within the Colorado River drainage basin. It towers 800 feet (240 m) above the Fremont River and State Route 24. This geological feature's dome-like shape reminded early explorers and settlers of capitol buildings, and lent the park its name.
Geology
Capitol Dome is composed of Navajo Sandstone, which is believed to have formed about 180 million years ago as a giant sand sea, the largest in Earth's history. In a hot, dry climate, wind blew over sand dunes, creating large, sweeping crossbeds which date to the Jurassic. Long after the sedimentary rocks were deposited, the Colorado Plateau was uplifted relatively evenly, keeping the layers roughly horizontal, but Capitol Reef is an exception because of the Waterpocket Fold, a classic monocline, which formed between 50 and 70 million years ago during the Laramide Orogeny.
