Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Sand Mountain Field
The Sand Mountain cinder cones rise to the WNW in late Spring across the still partially frozen surface of Big Lake. South (left) and North Sand Mountain cones are the largest of a group of 23 cinder cones along a N-S line immediately west of the Cascade crest, NW of Mount Washington. A series of young, sparsely vegetated lava flows reaching the valley of the McKenzie River originated from vents on the west side of the chain of cones and were erupted primarily during a 1000-year period from about 3000-4000 years ago.
