Mount Cirrus
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.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).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.[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.
