The Tenmile Range is an extension of the Mosquito Range, both part of Colorado's Rocky Mountains. The ranges are demarcated by the Continental Divide, with Tenmile on the west side. Peak 1 and Quandary Peaks serve as the northern and southern most boundaries of the range. Several of the higher numbered peaks in the range mark the upper boundary of Breckenridge ski resort. The range is ~11.8 miles in length from the summit of Mt. Royal (subpeak of Peak 1) to the summit of Quandary Peak.

Depending on the peak and season you may find a line of peakbaggers or see not another soul. Ed F has an interesting write-up on the history and geology of the range.

Peaks include:

Mt. Royal (10,502 feet), subpeak of Peak 1
Mt. Victoria (11,785 feet), subpeak of Peak 1
Peak 1 (12,805 feet)
Tenmile Peak, aka Peak 2 (12,933 feet)
Peak 3 (12,676 feet)
Peak 4 (12,866 feet)
Peak 5 (12,855 feet)
Peak 6 (12,573 feet)
Peak 7 (12,655 feet)
Peak 8 (12,987 feet)
Peak 9 (13,195 feet)
Peak 10 (13,633 feet)
Father Dyer Peak (13,615 feet)
Crystal Peak (13,852 feet)
Mt. Helen (13,164 feet)
Pacific Peak (13,950 feet)
Fletcher Mt. (13,951 feet)
Quandary Peak (14,265 feet)

Getting There

The trailheads are easily accessed from highways I-70, CO 91, and CO 9 out of Frisco and Breckenridge. Access options range from a hike or bike to a chairlift during ski season.

There is already an area on MP for climbs in or above 10 Mile Canyon, Quandary Peak, Pacific Peak, and Blue Lakes. This climb would be better posted under 10 Mile Canyon. The traverse from Peak 1 to to Quandary is rated 5.6 R/X if you stay on the ridge proper and is a fine winter outing. It's kind of a POS rubble romp. Sep 11, 2013

I reviewed the area hierarchy options before creating this page. 10 Mile Canyon is listed as a cragging area. It makes no sense to nest a range under a canyon. The alpine rock section notes the Mosquito Range as an example under this area. As Tenmile Range is an extension of the Mosquito Range, it seemed more appropriate as listed. If anything, Quandary should go under the range.

P.S. Your comment is under the wrong page, btw. It should go under route. Sep 11, 2013

I agree with Fossana. If anything, Quandary Peak should be moved so that it is under Tenmile Range. Sep 11, 2013

Okay, in concept, having this area separate from 10 Mile Canyon is logical. Moving Quandary Peak here is a bit problematic as there would be a child - parent incompatibility (i.e. you can't have areas and routes at the same level in the hierarchy for the website). If we make yet another sub-area for the 10 Mile Traverse, then we can put Quandary Peak at that level. You'll need an admin to do this minor reorganization once we have the sub-area under Tenmile Range for Tenmile Traverse.

Taylor, this site is sort of built by an organic process. We have to make adjustments over time to make it all work. Eventually it does. Sep 11, 2013

I totally agree with all of you, the Summit County area is getting kinda of scattered on MP. I'm all for having it under The Ten Mile Range.

Nice job, Fossana, on getting after such a choss fest, I would have never thought that another climber would show any interest in that traverse. Sep 28, 2013

Thanks, Taylor. It seems to be somewhat popular in the peak bagging circles based on the number of TRs. Nov 13, 2013
