North
Eolus
North Eolus rises from the same summit massif as Mount Eolus, a few hundred feet along a connecting ridge, and shares its 1874 naming history: Hayden Survey topographers called the main peak Aeolus for the Greek wind god, and the spelling settled into Eolus after the 1878 Wheeler Survey passed through. The subpeak sits inside the Weminuche Wilderness, land the Weminuche band of the Ute Nation hunted and held sacred before miners and surveyors arrived in the 1870s and 1880s.
With only about 179 feet of prominence above its saddle with Mount Eolus, North Eolus falls well short of the 300-foot rule used to count it as an independent fourteener, and no separate first-ascent record exists for it. Climbers bag it almost exclusively as a short, easy Class 3 add-on after summiting Eolus proper, crossing the connecting saddle in twenty minutes or so before continuing on to Sunlight and Windom peaks across Chicago Basin.
