Strawberry Mountain, the highest peak in the Strawberry Mountains of eastern Oregon, is the most prominent landmark in the Strawberry Mountain Wilderness and the 30th highest point in the state. Named for nearby Strawberry Creek by homesteader Nathan Willis Fisk because of abundant wild strawberries, it was once commonly called Strawberry Butte. The peak preserves a deep geologic record, from Early Jurassic volcanic and marine sedimentary rocks to andesitic eruptions about 16 to 14 million years ago that built much of the mountain. Later compression, erosion, and glaciation reshaped the range, exposing its inner structure and helping create valleys, alpine lakes, and fossil-bearing deposits in the John Day River Valley.
