Snow-capped Lassen Peak is seen here from the summit of Prospect Peak shield volcano at the NE end of Lassen Volcanic National Park.  The unvegetated, largely snow-free peaks on the right horizon are the Chaos Crags, a complex of dacitic lava domes last active about 1100 years ago.  The Twin Lakes sequence of andesitic lava shields and cones forms the lake-studded area of the Central Plateau in the center of the photo. Photo by Lee Siebert, 1998 (Smithsonian Institution).
