Mount Cirrus is a 12,808-foot-elevation (3,904-meter) mountain summit in Colorado, United States.

Description

Mount Cirrus is situated on the Continental Divide along the boundary shared by Grand County and Jackson County.^[5] It is the third-highest peak of the Never Summer Mountains which are a subrange of the Rocky Mountains.^[6] The mountain is situated on the western boundary of Rocky Mountain National Park and is visible from Trail Ridge Road within the park. The west side of the peak is in the Never Summer Wilderness, on land managed by Medicine Bow–Routt National Forest. Precipitation runoff from the mountain's west slope drains into tributaries of the Michigan River and the east slope drains into headwaters of the Colorado River except a portion which is diverted by the Grand Ditch. The counterintuitive direction of water flow is because the Continental Divide forms a loop in this area, whereby the peak's west slope runoff flows to the Atlantic Ocean and the east slope to the Pacific. Topographic relief is significant as the summit rises 3,600 feet (1,100 meters) above the Colorado River in three miles (4.8 km) and 2,600 feet (790 meters) above the South Fork Michigan River in one mile (1.6 km).

Etymology

The mountain's toponym was applied in 1914 by James Grafton Rogers,^[7] and was officially adopted in 1932 by the United States Board on Geographic Names.^[2] Rogers also named Mount Cumulus and Mount Nimbus, with the three names referring to different types of common clouds. As President of the Colorado Geographic Society, Chairman of the Colorado Geographic Board, and President of the American Alpine Club, Rogers participated in naming many of Colorado's mountains.^[8] The north ridge of Cirrus, officially named Hart Ridge, is named in remembrance of Eldon Charles Hart, Jr., of the Kansas Air National Guard, who was killed in the crash of his plane on this ridge on January 30, 1967, at age 26.^[9]

Climate

According to the Köppen climate classification system, Mount Cirrus is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.^[10] 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.

The Never Summer Mountains are a mountain range in the Rocky Mountains in north central Colorado in the United States consisting of seventeen named peaks. The range is located along the northwest border of Rocky Mountain National Park, forming the continental divide between the headwaters of the Colorado River in Rocky Mountain National Park to the local-east and the upper basin of the North Platte River to the local-west; the continental divide makes a loop in these mountains. The range is small and tall, covering only 25 sq mi (65 km²) with a north–south length of 10 mi (16 km) while rising to over 12,000 ft (3,700 m) at over ten distinct peaks. The range straddles the Jackson-Grand county line for most of its length, and stretches into Jackson and Larimer county at its northern end. A panoramic view of the range is available from sections of Trail Ridge Road in Rocky Mountain National Park. One of the northernmost peaks, Nokhu Crags, is prominently visible from the west side of Cameron Pass.

Mount Richthofen is the highest summit of the Never Summer Mountains range of the Rocky Mountains of North America. The prominent 12,945-foot (3,946 m) peak is located 5.6 miles (9.0 km) northwest by west of Milner Pass, Colorado, United States, on the Continental Divide separating the Rocky Mountain National Park Wilderness in Rocky Mountain National Park and Grand County from Routt National Forest and Jackson County. The mountain was named in honor of pioneering German geologist Baron Ferdinand von Richthofen, apparently by Clarence King's 1870 survey team.
