The dramatic summit pinnacle of Mount Washington is a central lava plug that caps a shield volcano. Mount Washington has been extensively dissected by glacial erosion, revealing the inner structure of the volcano. Fresh lava flows from cinder cones near North Sister volcano appear in the foreground of this view from the SE.
