Photo Gallery

Diamond Craters in SE Oregon is a 60 sq km volcanic field consisting of basaltic lava flows and numerous cones and craters. The central vent complex in this photo formed as a result of explosive eruptions from as many as 20 craters and cones. The age of the latest volcanic activity is not known precisely, but could be as young as late Pleistocene or early Holocene.

Lava flows of West Dome, one the structural highpoints of Diamond Craters, rise NE of lake-filled Malheur Maar. The shallow 2-m-deep lake occupies one of many maars (the rest of which are dry) of the Diamond Craters volcanic field. Diamond Craters consists of a 60 sq km area of basaltic lava flows, cinder cones, and maars that form a unique geologic environment in the high desert country of SE Oregon. Initial eruptions of pahoehoe lava flows were followed by magma injection that produced six structural highs of up to 120 m.
