Colorado 13er · South Ridge over Tundra Top

Is it right for you?

Cataract Peak sits just north of Tundra Top in the Pole Creek high country south of Lake City. Some lists also call it UN 13,524 A. The easiest way up goes over the top of Tundra Top.

Follow the Colorado Trail west from Carson Pass, climb Tundra Top, and then follow the ridge north to a saddle. From there, game and sheep paths lead to a southwest ridge. About 300 feet of it is steep, very loose, fine scree, and a small band of cliffs sits near the top. That scree makes it Class 2.

The round trip is about 10 miles with 1,900 feet of gain. Without 4WD, the Cataract Gulch trail to Cataract Lake is the other way in. Many people backpack in and add Carson Peak and other nearby summits.

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

Carson Pass

Find it on a map

From Lake City, head south on Highway 149 and turn right on County Road 3 (BLM 3306, shown as CR 30 on some maps) toward Lake San Cristobal. It's paved past the lake, then turns to good gravel that any car can drive. About 2 miles beyond Williams Creek campground, turn left (south) onto the Wager Gulch road (BLM 3308 or FS 568), signed for the old Carson townsite.

From that turn, plan on 4WD with good clearance. The road climbs through aspen and evergreens, steep in spots, to the Carson ruins. Above Carson it gets rockier and runs through willows for about the last mile to Carson Pass at 12,370 feet. Recent grading has made it easier, but it is still slow, and conditions change. If the top part makes you nervous, park near Carson and walk up.

You'll find Forest Service campgrounds at Mill Creek, Williams Creek and Lake San Cristobal. Wager Gulch has a few level primitive spots; a good one is a meadow on the west side of the road just before the Carson turnoff, near 11,240 feet. Beetles have killed many trees around it, so check above your tent before you pitch it.
