Ruby Mountain (Colorado)

Ruby Mountain is a 13277 ft mountain summit in Summit County, Colorado, United States.

Description
Ruby Mountain is set less than two miles west of the Continental Divide in the Front Range which is a subrange of the Rocky Mountains. The mountain is located 12 mi east of the community of Dillon and is set on land managed by White River National Forest. Precipitation runoff from the mountain drains into Peru Creek → Snake River → Dillon Reservoir → Blue River → Colorado River. Topographic relief is significant as the summit rises 2400 ft above Peru Creek in one mile (1.6 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names.

Climate
According to the Köppen climate classification system, Ruby Mountain is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers. 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. Climbers can expect afternoon rain, hail, and lightning from the seasonal monsoon in late July and August.
