Often veiled in clouds, Snowmass Mountain was called "the Cold Woman" by the Ute Indians, who believed the peak was the source of all weather in the area. Early pioneers called the mountain "White House Peak" as a complement to nearby Capitol Peak, and miners called it "The Twins" for its two (north and south) summits. The name "Snowmass" was given to the mountain by the Hayden Survey, for the prominent mass of snow that lies in the large amphitheater on the mountain's East Face.
