Colorado, United States
Mount Eolus is a fourteener in the U.S. state of Colorado, the highest of the Needle Mountains (a subrange of the San Juan Mountains). It is located in the Weminuche Wilderness (part of the San Juan National Forest) in La Plata County approximately 13 miles (21 km) south of Silverton.
Mount Eolus is one of three fourteeners in the Needle Mountains; the others are Sunlight Peak and Windom Peak. All three peaks are located around the cirque known as Upper Chicago Basin. Eolus lies to the west of the upper basin, while the other peaks lie on the east side. These peaks are among the most remote of the fourteeners and have a strong wilderness character. Windom Peak is only 1 foot lower than Mount Eolus; some sources have Windom being slightly higher than Eolus.
North Eolus (14,039 ft) is a northern subpeak of Mount Eolus, which is not usually counted as a separate peak or as an official fourteener, since it has a topographic prominence of only 159-199 feet. However it is sometimes climbed in conjunction with Eolus.
