Central Oregon is a perfect window into our state’s volcanic past. Some of the peaks visible from Redmond are extinct volcanoes; others are merely dormant. The smaller peaks are various byproducts of volcanic activity, from cinder cones to rhyolite domes. The tallest peak visible from Redmond is Mount Jefferson, at 10,497 feet. It last erupted around the year 950. Mount Washington is not far behind, at 7,794 feet. Scientists think it last erupted around the year 670. The Three Sisters, less commonly known as Faith (North Sister, at 10,085 feet), Hope (Middle Sister, at 10,047 feet), and Charity (South Sister, at 10,358 feet), are iconic. Only the North Sister is considered extinct; the youngest peak, South Sister, is the one most frequently tackled by climbers. Three Fingered Jack lies south of Mount Jefferson and stands at 7,844 feet. Many smaller promontories are visible from Redmond: Tetherow Butte is sometimes called Cinder Butte by locals. Cline Buttes are a popular recreation site with many trails. In the distance stands Black Butte, a 6,436-foot cinder cone that last saw volcanic activity some 1.4 million years ago. Gray Butte and Powell Buttes, to the north and east of Redmond, both stand at about 5,000 feet. Modest Forked Horn Butte, within city limits, is barely 200 feet higher than Redmond itself.
