Diamond Peak in Central Oregon is a slumbering shield volcano that rises to an elevation of nearly 9,000 feet. It last erupted 10,000 years ago, making it dormant, perhaps extinct. This 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. Crafted to last a lifetime, this blanket is woven from pure virgin wool in our Pendleton, Oregon, mill.
