This 'reef' is nowhere near the sea…

…nor near the U.S. Capitol building it's named for. Utah's Capitol Reef National Park—first established as a national monument this day in 1937—is named for its massive rock domes that reminded explorers of the famous rotunda in Washington, D.C. Why Capitol 'Reef,' though? Because the imposing formations were a major obstacle to travellers through the region, the same way a coral reef is an obstacle to sailors.
