Overview

Outcrops of volcanic conglomerateOutcrops of volcanic conglomerate

Thirtynine Mile Mountain is a bulky, hulking Elevener with over 2,000 feet of prominence in the rolling volcanic hills of southern Park County. A remnant of the Tertiary Period Guffey Volcano (inactive for about 30 million years) in the Thirtynine Mile volcanic field, Thirtynine Mile Mountain is studded with outcrops of red volcanic conglomerate.

In addition to its prominence (the 76th most prominent peak in Colorado, per the "Colorado's Most Prominent Peaks" list on SummitPost by SP member RyanS), a further attraction to Thirtynine Mile Mountain is that the mountain is not cut by any trails, all but ensuring a sense of solitude and isolation en route to the summit. While the summit is shrouded in trees, many fine views are available en route to the top along the undulating East Ridge. Views from outcrops studding this peak include the Sangre de Cristo Mountains and Pikes Peak.

Immediately Surrounding the Peak
This peak is very dry and the soil well-drained, thus reliable water sources are scarce. Camping right near the peak cannot be recommended.

Weather & Seasons

Zone Forecast for Guffey, CO

Southwest from the ridgeSouthwest from the ridge

Summer: Summitting this peak would be pretty hot (due to relatively low altitude) in the summer, though the trees shading the slopes would provide relief.

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 – bring a snorkel.

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, barring a major blizzard (the roads in this area are prone to wind-drifting). Expect some deep snow wallowing where the trees are thick during a winter ascent.
