Global Volcanism Program | Image GVP-06580

Minor amounts of basaltic lava were erupted about 3000 years ago from spatter cones at Black Crater and Ross Chimneys on the lower northern flank of Medicine Lake volcano.  The spatter cone in the foreground was the vent for the sparsely vegetated small overlapping pahoehoe lava flows in the middle part of the photo.  The dark lava flow in the distance in front of a fault block of older lavas, is the late-Pleistocene Devils Homestead lava flow.   Photo by Lee Siebert, 1988 (Smithsonian Institution).
