Named after the Greek god of the wind, the mountain was originally referred to as "Aeolus" in the 1874 Hayden Survey.[5] The current spelling of "Eolus" was first used in the Wheeler Survey of 1878.[6]

Climbing

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 mountains are among the most remote of Colorado's fourteeners and have a strong wilderness character.

North Eolus, elevation 14,045 ft (4,281 m), is a northern subpeak of Mount Eolus, though it is not usually counted as a separate peak or as an official fourteener, since it has a topographic prominence of only 179 ft (55 m).[7] It is sometimes climbed in conjunction with Eolus.[8]
