plan led in part to the proclamation of Sunset Crater Volcano National Monument by President Herbert Hoover in 1930. A 1-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, north of Flagstaff, Arizona, along U.S. Highway 89. In April 2022, the Tunnel Fire burned over the entirety of the monument, though the visitor center was spared. In December 2022, 98 acres including the visitor center and administrative facilities were transferred from Coconino National Forest to the national monument. Climate According to the Köppen Climate Classification system, Sunset Crater has a Continental climate, abbreviated "Dsb" on climate maps.
