Mount Jasper is a 12923feet mountain summit on the boundary shared by Boulder County and Grand County, in Colorado, United States.[4]
Mount Jasper is set on the Continental Divide in the Front Range which is a subrange of the Rocky Mountains.[3] The mountain is located 23miles 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 2100feet above Jasper Lake in two miles (3.2 km) and 3000feet above Cabin Creek in two miles. An ascent of the peak involves hiking 7miles with 3010feet of elevation gain.[5] The mountain's toponym was officially adopted in 2003 by the United States Board on Geographic Names.[4] Prior to that, it was called Jasper Peak.[4]
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.
