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.

Colorado 13er · South Ridge from Rock Creek

Overview

P 3 (once called UN 13,300 D) is a rocky peak south of Rock Creek in the Weminuche Wilderness. It's one of the harder 13ers in the Rock Lake area: a steep bushwhack, a boulder-filled basin and a loose ridge. Most people climb it from a camp at Rock Lake as part of a multi-day trip.

Rock Lake is about 9.9 miles from the Hunchback Pass trailhead by the Vallecito and Rock Creek trails. From there you walk back down the Rock Creek trail, cross the creek, climb through cliffy forest to a basin with two tarns, cross a rock glacier to the saddle between P 2 and P 3, and follow the ridges to the top. It's at least Class 3 and may be Class 4.

The round trip is about 26.8 miles with 8,075 feet of gain. From Rock Lake it's about 7 miles and 3,275 feet.

Getting to the trailhead

Trailhead

Hunchback Pass

Find it on a map

This trailhead needs a high-clearance 4WD, and you should allow as much as two and a half hours from Silverton. From the northeast end of Silverton, take County Road 2 up the Animas about 4.2 miles to Howardsville. Turn right up Cunningham Gulch, then take the left fork onto the Stony Pass road. It climbs steeply over the pass and down the far side. You will ford Pole Creek, then turn right at a fork and ford the Rio Grande. Both fords are harder early in the summer. Then follow the Beartown road about 4 slow, rough miles past the old Beartown site and up a rocky, rutted stretch. The Hunchback Pass trailhead is about half a mile below Kite Lake, at roughly 11,800 feet, with limited parking.

You can also reach this area from Creede or Lake City by driving to Rio Grande Reservoir, but the road west of the reservoir has very rough sections. There is some camping near the trailhead and near the old Beartown site.

Conditions on Stony Pass and the Beartown road change from year to year, so check before you go. Trips from here into the Weminuche usually take several days.

Less traffic, less margin

This describes the route on a dry summer day. Most 13ers see few people, so there may be no one along behind you. Check recent conditions the week you go, carry a map, tell someone your plan, and turn around when the day tells you to.
