Bartlett Mountain is located in the Tenmile/Mosquito Range less than one mile northwest of Clinton Peak. Bartlett Mountain was once the largest source of molybdenum in the world. Since its mining, the summit has been lowered from 13555' to 13400'. The new elevation has been measured at both Bartlett's summit and the Bartlett-Little Bartlett saddle by Gerry Roach. Bartlett Mountain is still ranked despite this elevation loss.

Bartlett now has 460' of prominence and is the 322nd highest peak in Colorado. The new summit is very loose and looks like it will topple over soon. Bartlett Mountain's west face is scarred, but it's north face shows little signs of mining and provides a fun ski descent. The summit provides good views of Clinton Peak, Mount Arkansas and Wheeler Mountain. Mining operations are scheduled to resume in 2010.

Getting There

Clinton Reservoir Trailhead
Drive 7.6 miles south from the Colorado 91/Interstate 70 intersection or 3.6 miles north on Colorado 91 from Fremont Pass. The trailhead is on the east side of the road and is plowed in the winter.

West Face Route
Hike southeast looking for a natural gas line. Follow the natural gas line, then a rough road, then travel cross country to Little Bartlett Mountain's northwest face. Gain the mining road on Bartlett Mountain's west face and follow to the base of Bartlett Mountain's west ridge. Follow the ridge to the summit. The summit has a summit register tube, but no lid or register. Climb the summit block to the summit (Class 3+). The summit block is exposed and loose and feels like it will crumble below you when climbing it.

Red Tape

The entire, aforementioned West Face Route is on private land owned by Climax Molybdenum Company, as indicated by signage at Clinton Reservoir. There are currently no "No Trespassing" signs en route as of 11/2008 (SarahThompson).
