Snowmass
Mountain
Approach only — the mapped line ends where OpenStreetMap ends, below the summit; the scramble to the top is unmapped.
William Byers, James Gardner, and W. Rideling of the Hayden Survey made the first recorded ascent on August 7, 1873, naming the mountain for the large permanent snowfield on its eastern slopes. Byers, who founded the Rocky Mountain News in 1859 and was among Colorado's most prominent civic boosters, and Gardner, a survey topographer, were mapping the Elk Mountains for the first time on that expedition.
Snowmass Mountain sits in the Maroon Bells-Snowmass Wilderness along the Pitkin-Gunnison county line, reached by a long approach past Snowmass Lake below its eastern flank. It is frequently confused with the separate, lower Snowmass Peak nearby, whose sharper profile is more often photographed despite falling short of fourteener status, and with the Snowmass ski resort in Snowmass Village, which sits in an entirely different valley to the northeast.
SOURCE Wikipedia — Snowmass MountainNo day-use fee (14ers.com er04/snow1, checked July 2026). Snowmass Lake sits in the Four Pass Loop permit zone of the Maroon Bells-Snowmass Wilderness, so the usual 2-day itinerary (camp at the lake) requires a recreation.gov overnight permit (ID 4675333; $10/person/night May-Oct + $6 fee; very limited in summer; 2026 blocks released Feb 15 and Jun 15). Dispersed camping near the log jam ~2 mi below the lake is the permit-free fallback; a single-day push is 22 mi.
