Sunset Crater Volcano National Monument

Sunset Crater Volcano National Monument is a U.S. National Monument in the north-central part of the U.S. state of Arizona, intended to protect Sunset Crater, a cinder cone that is part of the San Francisco Volcanic Field. It is maintained 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.
