Colorado 13er · North-Northwest Ridge

Is it right for you?

Corbett Ridge (UN 13,107) is a small summit at the far east end of the Sneffels Range, overshadowed by Whitehouse Mountain next door. It is reached from the north, out of Ridgway.

From the upper trailhead, a rough road leads to big meadows by the Burn Hut. Game trails lead through the trees to the north ridge and across to the main north drainage, then a steep, loose slog up the north-northwest ridge reaches a false summit. An outward-sloping ledge around the east side of the summit block reaches the true top, only about 10 feet higher. It is Class 2+.

From the upper trailhead the round trip is about 8 miles with 3,680 feet of gain. Driving to the end of the road near the Burn Hut saves about 1.1 miles each way and about 330 feet. From the lower lot, the round trip is close to 16 miles.

Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.

Getting there

Trailhead

Upper Miller Mesa

Find it on a map

In Ridgway, head west on CO 62 and turn left on the last street you can, South Amelia Street. Go about three blocks south and turn right on County Road 5. Follow this graded dirt road about 5.3 miles up onto Miller Mesa to Elk Meadows, where a large parking area sits at a junction. Passenger cars should stop here.

Higher-clearance vehicles can go on south-southeast on Forest Road 852. It loops around a low hill, past a view down into Beaver Creek, along an old ditch, and down to cross a fork of Coal Creek. At a gate, 3.7 miles from the lower lot, it enters National Forest. About 0.4 mile farther, the road turns sharply east. This bend, at about 9,430 feet, is the upper trailhead, with good camping nearby. Starting from the lower lot adds about 4 miles each way and about 700 feet of gain.

There are a few primitive sites along FR 852 below the gate, but they may be on private land. The upper trailhead should be on National Forest land.
