Details for: San Francisco Volcanic Field
Snow-mantled Sunset Crater (left-center), seen from O'Leary Peak to the NW, is the youngest volcanic feature of the San Francisco Mountain volcanic field, which covers a vast area of northern Arizona between Flagstaff and the Grand Canyon. The Sunset Crater eruption began about 1100 CE from a chain of cinder cones and vents trending NW-SE, the largest of which is Sunset Crater. Three lava flows were erupted, the longest of which traveled 11 km to the NE. Photo by Ed Wolfe, 1973 (U.S. Geological Survey).
