Details for: Adams
Mount Adams rises above a cloud layer filling valleys in the Cascade Range, viewed from High Knob, NW of the volcano. Adams is constructed on a lower base than its neighbor Mount Rainier, and has a larger volume. Unlike Mount Rainier, where eruptions have mostly been restricted to the summit conduit, Mount Adams has also produced eruptions from numerous flank vents surrounding the volcano. A series of lava flows were erupted on the north, NW, south and east flanks between about 7000 and 1000 years ago. Photo by Lee Siebert, 1981 (Smithsonian Institution).
