Is it right for you?
Quarter Peak is an unnamed summit near Cataract Lake, Half Peak and Pole Creek Mountain. It is Class 2 but a bit steeper and looser than its neighbors. Some online imagery puts the summit in the wrong place, so check your map.
From a base camp near the Divide trail, you go down to the small lakes northwest of Cataract Lake, climb a grassy gully, cross a big talus basin on the east side of the peak, and finish up the north ridge. Most people backpack to a base camp. The broad tundra ridge above Cataract Lake has big views and is central to a dozen 13ers, but it has no trees for shelter. Cataract Lake has easier water but sits lower, so each climb gains more.
From Carson Pass the round trip is about 19.9 miles with 3,315 feet of gain. From the trail junction near camp it is about 9.5 miles and 2,415 feet. The ridge from Half Peak has a narrow neck with spires, so most people link the two by going around the east side.

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
Carson Pass
From Lake City, drive south on Highway 149 and turn right onto County Road 30 toward Lake San Cristobal. Pavement lasts until you are beyond the lake; after that the road is graded dirt that any car can drive. Roughly 2 miles beyond Williams Creek campground, go left (south) on the Wager Gulch road toward the old town site of Carson.
From this turn, 4WD with good clearance is best. The road climbs through aspen and conifer forest, steep in places, to Carson. Above Carson it gets rockier as it climbs through willows to Carson Pass at about 12,370 feet. Recent grading has made it easier, but it is still slow. If you are not comfortable with the last mile, park near Carson and walk. A few primitive campsites line the road below Carson, though many dead trees stand around them.
Just south of the pass, a junction of several tracks is a good place to park. A 4WD can save about 0.6 mile of walking by taking the road southwest to where the good road ends at a viewpoint. On the way down that road, the Continental Divide / Colorado Trail (Trail 787) leaves on the right at about 12,100 feet, marked by a post. You can also start from the Cataract Gulch trailhead near Sherman, which any car can reach, but that adds about 2,500 feet of climbing over roughly 4.5 miles to Cataract Lake. For a developed campground, try Williams Creek, Mill Creek or the ones by Lake San Cristobal.
