Mount Heyburn is located in the Sawtooth National Recreation Area about one mile west of Redfish Lake (drive to this 5 mile long lake). From Highway 93 it appears as the most prominent peak in the Sawtooth Range even though it is not the highest.
Mount Heyburn has two summits separated by a deep notch. The western summit is higher by just a few feet. Most of the mountain is composed of very decomposed granite. The Stur Chimney is one of the most popular routes on the peak and avoids most of the poor rock. Beautiful, multi-towered summit, Sawtooth granite. Some of approach near the peak is soft (ball-bearing) scree. Some of the mountain is soft and rotten. A rich climbing history inlcudes ascents by the Underhills, the Iowa Mountains, Louis Stur, Fred Becky. Stur Chimney first ascent by Louis, good sold rock.
