The Blowouts, the spatter vents in the foreground, are the source vents of the voluminous Devils Garden lava field. Devils Garden is the NW-most of a group of three lava fields SE of Newberry volcano and contains 117 km² of overlapping pahoehoe lava flows erupted from fissure vents at the NE part of the field. The extremely fluid and inflated pahoehoe lavas typically left flows that increase from about a half meter thickness near the vent to about 5 m in the distal portion. The lava flows are either late Pleistocene or early Holocene in age.
