Mt. Washburn is the main peak in the Washburn Range, rising 10,243 ft. above the west side of the Canyon. It is the remnant of volcanic activity that took place long before the formation of the present canyon. It is an excellent example of subalpine habitat and is very accessible to the average visitor. Bighorn sheep and an abundance of wildflowers can be found on its slopes in the summer. Mt. Washburn was named for Gen. Henry Dana Washburn, leader of the 1870 Washburn-Langford-Doane Expedition.
