In central Oregon, Diamond Peak shows the marks of time. Rising to 8,748 feet, it was carved by glaciers into a range of mountainous subfeatures: Mount Yoran, Lakeview Mountain, and dramatic cinder cones. This slumbering shield volcano has not erupted in 10,000 years, making it dormant, perhaps extinct. The pattern’s peaks and valleys echo the landscape, part of the Pacific Crest Trail and ancestral territory of many Oregon tribes, including the Klamath, Modoc and Yahooskin peoples. Unnapped.
