Upper Cathedral Valley, Capitol Reef National Park, Utah, USA

Capitol Reef National Park is an American park in Utah's south-central desert. It is named after its massive rock domes that reminded explorers of the dome of the United States Capitol building in Washington, DC. Locally, 'reef' refers to any rocky barrier to travellers through the region, the same way a coral reef is an obstacle to sailors.
