BeschreibungMost of the 23 basaltic and basaltic-andesite cinder cones of Sand Mountain volcanic field are aligned along a N-S trending line immediately west of the Cascade crest NW of Mount Washington. A secondary trend of alignment in NNW and NNE direction intersects the N-S line near the largest cinder cone, Sand Mountain.
Geologically young lava flows from vents on the western side were erupted between 3000-4000 years ago. The lava flows traveled mostly to the west, blocking local drainages and forming several small lakes.
