Colorado 13er · West Slope over Hanson Peak

Is it right for you?

UN 13,078 sits east of Hanson Peak at the head of Placer Gulch, above Animas Forks. It was once listed as UN 13,075. A 4WD road crosses the saddle just west of it, so a driver can park less than 400 feet below the top.

This route climbs Hanson first, then crosses to the saddle above Parson Lake, either along the connecting ridge (Class 2 tundra and scree) or down Hanson's east side and east along the road. From the saddle it is about 400 feet up tundra, then a little chip rock on a narrow summit ridge. The peak itself is Class 1.

Hanson to UN 13,078 is about 1.25 miles and 435 feet of gain one way. Climbing both from the trailhead and walking back down the road is about 7.5 miles round trip with 2,335 feet of gain. Mileage and gain are our estimates.

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

California - Placer Gulch

Find it on a map

From Silverton, drive east through town. A block beyond the courthouse the paved road splits; bear right onto County Road 2, which has a blue sign. It is also called the Alpine Loop road. Pavement ends after about 2 miles, and good dirt road goes on to Howardsville at 4.2 miles. Keep north 4.3 more miles to the old Eureka site. Past there the road switches to the river's west bank, climbs a steeper shelf and runs up a narrower part of the canyon.

Near 10,740 feet the valley widens and the Picayne Gulch road goes left. Its lower part is very steep and only for 4WD vehicles with low gearing. Most people stay on the main road and take the left turn to Animas Forks; the first of the two turnoffs drops across the river and climbs up to the old mining town. From there head west on County Road 19 (BLM 4505). Maps disagree on whether this road needs 4WD; a high-clearance vehicle is wise. After 1.2 miles you reach the Placer Gulch road (County Road 9) on the left. This junction with California Gulch is the trailhead.

With a good 4WD you can drive up Placer Gulch. The road is fine to about 12,200 feet, then turns rockier on switchbacks at the Gold Prince Mine. At 12,600 feet a short spur goes south and makes a good place to park. The road goes on east to a saddle above Parson Lake, then drops very steeply down Picayne Gulch to the main road. Heavy ATV and 4WD use may have made it worse, so check current conditions. There are no Forest Service campgrounds up here. Eureka has a pay campground that takes reservations, and there are primitive sites on the spur road to the South Fork of the Animas (Boulder Gulch) trailhead and on a side road in the trees in Picayne Gulch. None have services.
