Description
Mount Jasper is set on the Continental Divide in the Front Range which is a subrange of the Rocky Mountains.[4] The mountain is located 23 miles (37 km) west of Boulder in the Indian Peaks Wilderness, on land managed by Arapaho National Forest and Roosevelt National Forest. Precipitation runoff from the mountain's east slopes drains into Jasper Creek and Boulder Creek, whereas the west slope drains to Fraser River via Cabin Creek. Topographic relief is modest as the summit rises 2,100 feet (640 m) above Jasper Lake in two miles (3.2 km) and 3,000 feet (914 m) above Cabin Creek in two miles. An ascent of the peak involves hiking seven miles (11 km) with 3,010 feet (917 m) of elevation gain.[5] The mountain's toponym was officially adopted in 2003 by the United States Board on Geographic Names.[3] Prior to that, it was called Jasper Peak.[3]
Climate
According to the Köppen climate classification system, the mountain is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.[6] 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.
