Capitol Peak and Snowmass Mountain are composed of granites that intruded during the Tertiary Period towards the end of the Laramide orogeny (the event responsible for the uplift of the modern day Rocky Mountains).
These granites are rich in quartz, mica, and plagioclase.

Capitol Peak was named by the 1874 Hayden Survey. Although the Hayden Survey named Capitol Peak, they made no attempt to climb it. As one member of the survey team, Henry Gannett, put it: the peak's "prism-shaped top and precipitous sides forbid access."
