Chiefs Head Peak (Arapaho: Hookuhu'eeno) is a 13577feet mountain summit in Boulder County, Colorado, United States.
Chiefs Head Peak is set along the Continental Divide in the Front Range of the Rocky Mountains.[6] The mountain is situated within Rocky Mountain National Park and is the third-highest peak in the park.[7] It is also the third-highest peak in Boulder County.[8] Precipitation runoff from the mountain's south slope drains into North St. Vrain Creek, the north slope drains to Glacier Creek which is a tributary of the Big Thompson River, and the lower west slope drains to Grand Lake via North Inlet. Topographic relief is significant as the summit rises 2000abbr=offNaNabbr=off above Frozen Lake in one-half mile. The mountain's toponym was officially adopted in 1911 by the United States Board on Geographic Names.[3] The Arapaho called this peak hookuhu'eeno or "Head Mountain" because of a profile resemblance to a chief wearing a war bonnet.[9]
According to the Köppen climate classification system, Chiefs Head Peak is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.[10] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring.
