Mount Jasper is a 12,923-foot (3,939 m) mountainsummit on the boundary shared byBoulder County andGrand County, inColorado, United States.[3]
Mount Jasper is set on theContinental Divide in theFront Range which is a subrange of theRocky Mountains.[4] The mountain is located 23 miles (37 km) west ofBoulder in theIndian Peaks Wilderness, on land managed byArapaho National Forest andRoosevelt National Forest. Precipitation runoff from the mountain's east slopes drains into Jasper Creek andBoulder Creek, whereas the west slope drains toFraser 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 theUnited States Board on Geographic Names.[3] Prior to that, it was called Jasper Peak.[3]
According to theKöppen climate classification system, the mountain is located in an alpinesubarctic 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.
