Craters of the Moon, Idaho, a lava field that forms part of the Snake River Plain Volcanic Province in southern Idaho, covers approximately 1600 square km and contains over 30 cubic km of volcanic rocks. The Craters of the Moon lava field formed during 8 eruptive periods between 15,000 and 2000 years ago (Kuntz, et al. 1986). A range of rock types, from felsic trachytes to mesocratic basalts, erupted at Craters of the Moon (Stout, et al. 1994). This panoramic photograph shows a cinder cone (Inferno Cone) in the background and the surface of a Blue Dragon flow east of the main vents in the lava field. The Blue Dragon lava flows, with their pahoehoe surfaces, are home to numerous lava tubes.
