Sunset Crater Volcano National Monument is a U.S. National Monument in the north-central part of the U.S. state of Arizona, created to protect Sunset Crater, a cinder cone within the San Francisco Volcanic Field.The monument is managed by the National Park Service in close conjunction with nearby Wupatki National Monument.
In the late 1920s, a Hollywood film company attempted to detonate large quantities of explosives inside Sunset Crater in order to simulate a volcanic eruption.Public outcry over this plan led in part to the proclamation of Sunset Crater Volcano National Monument by President Herbert Hoover in 1930.
A one-mile (1.6 km) self-guided loop trail is located at the base of Sunset Crater but hiking to the summit is not permitted. A trail providing access to the summit and crater was closed in 1973 because of excessive erosion caused by hikers. A visitor center is located near the park entrance, 15 miles (24 km) north of Flagstaff, Arizona, along U.S. Highway 89.
