Gray Butte is a volcanic butte in the southeast corner of Jefferson County, Oregon, United States. It is composed of welded tuff and is a part of the Crooked River caldera.[2] A recreation trail for hiking, horseback riding, and mountain biking leads up the side of the butte.[3] The butte is located near the popular tourist site of Smith Rock.[4]
