Mount Arkansas is a 13795feet mountain summit in Lake County, Colorado, United States.
Mount Arkansas is set just east of the Continental Divide in the Mosquito Range, which is a subrange of the Rocky Mountains. It ranks as the 12th-highest peak in Lake County and the 107th-highest in Colorado.[3] The mountain is located 8miles northeast of the community of Leadville on land managed by San Isabel National Forest. It dominates the view from Highway 91 south of Fremont Pass. Precipitation runoff from the mountain's slopes drains into headwaters of the East Fork Arkansas River. Topographic relief is significant as the summit rises 3400feet above the river in two miles (3.2 km). An ascent of the peak involves hiking 7miles with 2900feet of elevation gain.[1] The mountain's toponym has been officially adopted by the United States Board on Geographic Names,[4] and has been recorded in publications since 1877.[5]
According to the Köppen climate classification system, Mount Arkansas 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.
