Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Rainier
Mount Rainier, seen here across a cloud-filled valley from High Knob SW of the volcano, forms a dramatic backdrop to the Puget Sound region. Large Holocene mudflows from this massive, heavily glaciated volcano have reached as far as the Puget Sound lowlands. Several postglacial tephras have been erupted from Mount Rainier; tree-ring dating places the last recognizable tephra deposit during the 19th century. Extensive hydrothermal alteration of the upper portion of the volcano has contributed to its structural weakness. Photo by Lee Siebert, 1981 (Smithsonian Institution).
