Mount Nimbus is a 12721feet mountain summit in Grand County, Colorado, United States.
Mount Nimbus is set along the Continental Divide and is the fifth-highest peak of the Never Summer Mountains which are a subrange of the Rocky Mountains.[5] 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 Arapaho National Forest. Precipitation runoff from the mountain's lower northwest slope drains into headwaters of the South Fork Michigan River and all other slopes drain into tributaries of the Colorado River except a portion which is diverted by the Grand Ditch. Topographic relief is significant as the summit rises 3700abbr=offNaNabbr=off above the Kawuneeche Valley in 3miles and 1700abbr=offNaNabbr=off above Baker Gulch in one-half mile.
The mountain's toponym was applied in 1914 by James Grafton Rogers,[6] and was officially adopted in 1932 by the United States Board on Geographic Names.[2] [7] Rogers also named Mount Cirrus and Mount Cumulus, 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] He also drafted legislation to create Rocky Mountain National Park.
According to the Köppen climate classification system, Mount Nimbus is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.[9] 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.
