Overview

 
At the summit of Threemile Mtn
At the summit of Threemile Mountain

Threemile Mountain juts out of the high prairie of southern Park County. It sits relatively isolated, and provides fine views in most directions from its rocky summit. This is a cool little peak with a rocky finish, and even in the dead of winter demands a relatively small price in terms of overall level of effort to reach its 10,000+ foot summit and enjoy the breeze and the views.

Like neighboring peaks in this area, Threemile Mountain rises out of a dry, grassy plain and has sparse, scrubby trees on its upper slopes and near its summit. The summit area is craggy enough to deter tree growth and provide fine views, even of the distant Sawatch.

Rank: 2,296th highest peak in Colorado

Weather & Seasons

East from the summit of Threemile Mountain

Summer: The route can be a bit hot and dusty in the summer, but the road should be dry and accessible and the breezes on top pleasant.

Spring: The snowpack is less deep here than in the high country and melts out faster than higher areas to the west. None-the-less, expect post-holing through unconsolidated snow drifts in the trees.

Fall: The aspen coating the slopes of this peak and surrounding neighbors make this area a golden-hued heaven in the fall.

Winter: Thanks to proximity to both US Hwy 24 Colorado Hwy 9, as well as to “primary dirt roads”, this peak is accessible year-round,except in blizzard conditions where drifting powder could block roads faster than highway crews can clear the snow.
