Mount Toll is a 12,979-foot (3,956 m) mountain summit on the boundary shared by Boulder County and Grand County, in Colorado, United States.[3]

Description

[edit]

Mount Toll is set on the Continental Divide in the Front Range which is a subrange of the Rocky Mountains.[4] The mountain is located 21 miles (34 km) west-northwest of Boulder in the Indian Peaks Wilderness, on land managed by Arapaho National Forest and Roosevelt National Forest. It is the seventh-highest summit in the wilderness and 16th-highest in Boulder County.[2] Precipitation runoff from the mountain's east slope drains into Blue Lake thence South St. Vrain Creek, whereas the west slope drains to Monarch Lake via Cascade Creek, thence Lake Granby. Topographic relief is significant as the summit rises 2,100 feet (640 m) above Pawnee Lake in 0.6 mile (1 km) and 1,660 feet (506 m) above Blue Lake in 0.65 mile.

Etymology

[edit]

The landform's toponym was officially adopted on November 19, 1940, by the United States Board on Geographic Names to honor Roger Wolcott Toll (1883–1936), American mountaineer, superintendent of nearby Rocky Mountain National Park (1921–1929), and author of The Mountain Peaks of Colorado.[3] He is also the namesake of Toll Mountain in Texas.

Climate

[edit]

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.
