Aspen Buttermilk's summit reaches 9,902 feet, dropping 2,031 vertical feet to a base at 7,868 feet across 44 runs spread over 469 acres near Aspen, Colorado. Terrain splits 39 per cent intermediate, 35 per cent beginner, 21 per cent advanced and 5 per cent expert. Average annual snowfall runs to roughly 210 inches. The resort carries Ikon Pass and Mountain Collective affiliation. Four lifts, including three quad chairs and one double chair, serve the mountain alongside four surface lifts.

Buttermilk serves as the beginner-friendly counterpart within the four-mountain Aspen Skiing Company portfolio, offering considerably gentler terrain than its sister mountains, Aspen Mountain, Aspen Highlands and Snowmass. Its role as the host of the Winter X Games has also given Buttermilk an unexpected international profile for a mountain built primarily around learning terrain.

Friedl Pfeifer, the Austrian ski instructor and racing champion who co-founded the Aspen Skiing Company in 1946, sold his interest in the company in 1958 and turned his attention to developing Buttermilk Mountain that same year, giving Aspen its dedicated beginner-focused ski area. Buttermilk subsequently joined the broader Aspen Skiing Company portfolio alongside Aspen Mountain, Highlands and, later, Snowmass.

Aspen Skiing Company's ownership has remained with the Crown family of Illinois since the mid-1980s, following the company's 1977 sale to Twentieth Century Fox and subsequent 1985 transition. Buttermilk continues to operate as the accessible, learning-focused member of the Aspen four-mountain family. Adult daily tickets run from 189 to 259 US dollars, matching pricing across all four Aspen Skiing Company mountains.
