Geotourism. The Flagstaff area, on the southern margin of the Colorado Plateau, offers an exceptional variety of geologic wonders. The landscape of this plateau is composed of remarkable geologic features: the towering, glaciated peaks of San Francisco Mountain, underground lava tubes and blowholes; meteor-blasted Barringer Crater, and cinder cones and lava flows of the San Francisco volcanic field.
