Cline Buttes are three rounded volcanic peaks in central Oregon west of Redmond, standing at the meeting point of the Cascade foothills and the high desert. Formed about 25 million years ago as a silicic volcanic center, they were later worn by erosion into dome-shaped summits. The area supports juniper, sagebrush, raptors, and other wildlife, and was used seasonally by Warm Springs peoples before the Treaty of 1855 ceded the land while preserving traditional rights. Named for pioneer dentist and developer Dr. Cass A. Cline, the buttes also saw a brief, unsuccessful gold rush in 1904 and are now a popular recreation area with broad summit views.
