Aerial view of Inyo Craters and Deer Mountain
Photograph by C.D. Miller in 1984

Aerial view toward the north of the Inyo Craters, Deer Mountain, and South Deadman flow. The Inyo Craters and the crater atop Deer Mountain were formed by a series of steam-driven explosions caused by magma heating the groundwater. Magma never reached the surface as it moved beneath this southern-most end of the Inyo Chain. Before these steam explosions, however, magma had already erupted at the north end of the Inyo chain, generating a series of highly explosive events and lava flows.
