  • Mount Eolus is a Colorado 14er within the Weminuche Wilderness in the Needle Mountains, a subrange of the San Juan Mountains.
  • Mount Eolus is one of 3 fourteeners in the Needle Mountains; the others are Sunlight Peak and Windom Peak. All 3 peaks are located around the cirque known as Upper Chicago Basin.
  • Eolus lies west of the upper basin, while the other peaks lie on the east side.
  • Among the most remote of the fourteeners and has a strong wilderness character.
  • Windom Peak is only 1 foot lower than Mount Eolus.
  • North Eolus (14,039 ft) is a northern subpeak of Mount Eolus, which is not usually counted as an official fourteener, since it has a topographic prominence of less than 300 feet. However it is sometimes climbed in conjunction with Eolus.
  • A popular way to access Chicago Basin is the Durango & Silverton Narrow Gauge Railroad. It will drop off/pick up hikers at the trailhead far from any road.
"Departed base camp in Chicago Basin and began hike of Eolus and North Eolus on July 4 at 4:30am, peaked Eolus at 9:10am, peaked North Eolus at 10:20. Began descent at 10:50, and got back to base camp at 1:35pm. Lots of hail and some lightning during the descent. CO 14er #31" - Globetrotter87, Jul 4, 2014
"Mt. Eolus, the highest peak in the Weminuche Wilderness, is a tough climb that shouldn't be underestimated. On the approach, you must cross a narrow, exposed section called the Catwalk. Then, once across the ridge, the final climb is an interesting puzzle of routefinding among grassy ledges and rock blocks. The summit is broad and flat, and the views from here are the best in the entire area. If I were to climb one peak from the Chicago Basin, this would be it. " - scott, Aug 28, 2006
