Kwohl Butte is one in a 25-km-long chain of scoria cones and small shield volcanoes south of Mount Bachelor in the central Cascade Range of Oregon. Despite the youthful appearance of the cone, geologic mapping indicates construction of the chain was completed about 12,000 years ago. Photo by Lee Siebert, 1981 (Smithsonian Institution).
