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.

Centennial 13er · South Slope

Overview

Clinton Peak is a rounded Mosquito Range summit at the head of the Middle Fork of the South Platte River, just east of the Climax Mine. From Montgomery Reservoir you walk a long, rough 4WD road up the valley to Wheeler Lake, climb a gully into a high basin, and finish on talus to the summit. Many people also add the nearby summits of Traver and McNamee.

The route is Class 2 with no exposure. It is a gentle mountain, but the day is long because of the road walk. The road is muddy and rocky, with big puddles that push you into the willows. Above the lake the terrain is open tundra, rock outcrops and talus.

The round trip is about 9 miles with about 2,950 feet of gain. Plan on 6 to 8 hours. It is a good choice for newer hikers who can handle distance, and for anyone who wants a quieter peak close to Breckenridge.

Plan of the day

Start by

By 6 a.m. The road walk takes a while, and you want to be off the upper slopes before afternoon storms.

Turnaround

If you are not at Wheeler Lake by 9:30 a.m., or clouds are building over the basin, turn around. Leave the summit by noon.

Crux

The last talus slope from the head of the basin to the summit. It is steady, loose and tiring, but never hard.

Route-finding

The road is easy to follow. Above Wheeler Lake, pick your way up a gully into the basin, then head to the basin's head and up to the summit. In clouds, the broad basin and ridges can be confusing.

Water

The Middle Fork and Wheeler Lake have water. Small streams in the upper basin may run early in the season. Filter everything; there is a lot of old mining in this area.

Getting to the trailhead

Trailhead

Montgomery Reservoir

Find it on a map

From Breckenridge, drive south on Highway 9 over Hoosier Pass. About a mile past the top, turn right (west) onto County Road 4. From Alma, drive north on Highway 9 about 5 miles and turn left onto CR 4. Follow CR 4 down to Montgomery Reservoir, ignoring side roads.

Right before you reach the dam, the road splits in two. Passenger cars should take the left branch, which drops to parking beside the lake. The right branch swings over to the reservoir's west end and a lot where the road ends; most stock SUVs can get there. Past that lot, the 4WD road toward Wheeler Lake opens with a rock slab and a tall step that turns back many vehicles, and conditions get much worse higher up. The trailhead has no real camping, and the land surrounding the reservoir is private.

Conditions change the route

This describes the route on a dry summer day. Snow, ice, a washed-out road or an afternoon storm can make it a very different climb. Check recent conditions the week you go and turn around when the day tells you to.
