Peak Summary

Although somewhat imposing and difficult looking from the road in upper Lincoln Creek, south of Grizzly Reservoir, UN13,631/Anderson Peak is actually a relatively easy Class 2 summit from its north and northwest ridge. A 4WD vehicle for access up Lincoln Creek can help greatly in reaching the peaks south of Grizzly Reservoir.

    • Lincoln Gulch - Grizzly Reservoir TH #2

      From the Town of Aspen, drive east up state highway 82 toward Independence Pass. A little past the Grottos TH, turn south (right) and drive down to the Lincoln Gulch Campground. If in a passenger car, you'll need to park here. If coming from the Front Range, drive to either Leadville or Buena Vista and turn onto SH 82 from US 24 at Twin Lakes. Drive up and over Independence Pass. On the west side of the pass, drive on past the Lostman CG, and in just under 4 miles will be the turnoff for the Lincoln Gulch CG. 4WD or vehicles with better ground clearance may then continue ESE for Grizzly Reservoir. This road is identified as CR23 or FS107. Along the first 3 miles to the New York TH, there are numerous, designated, primitive campsites. The road tends to be slow going with potholes, etc., but no real major obstacles. It may take over a half hour to drive the 6 plus miles back to the reservoir. There is a small campground there with toilet facilities called the "Portal" campground.

      Just past the campground, in prior years, we have found a locked gate across the road as it continues south up the valley. Because there are some private holdings further up valley, we've seen some persons with a key to that gate. We've seen the Forest Service keep that gate closed past the 4th of July weekend, depending on snow melt conditions. The gate may also be closed again in early fall. If the gate is open and you have good 4WD clearance, you may continue to drive up valley as far as "Ruby," and the Ruby Mine, right around, 11,400 ft. If the gate is closed, be prepared to walk an extra 4 miles, or do as we did one time , and bring mountain bikes and ride up the road as far as you need to go. The bikes won't seem much faster than walking when going uphill, but will speed your return to the campground considerably.

      Alternate Trailhead for Petroleum Pk: See the trailhead description for Tellurium Creek north of Taylor Park Res.


      There are two designated Forest Service campgrounds: The Lincoln Gulch CG and the Portal CG at Grizzly Reservoir. In addition, for the first 3 miles as you drive SE to Grizzly res., there are numerous (over 30?) "designated" primitive spots for camping. These have been marked by the Forest Service. On summer weekends, both campgrounds and all the designated primitive spots can be fully occupied. Seems to be a very popular area. If the road is open south of the Portal CG, there may be some other, usable primitive sites. Both the Portal and Lincoln Gulch CG have vault toilets, but neither has water.

    • From Lincoln Gulch - Grizzly Reservoir TH #2 via Anderson Lake TH

      As indicated in the trailhead description, there may be a locked gate beyond the Portal campground, blocking vehicle access further up Lincoln Creek. It appears that the Forest Service keeps this road closed beyond the Portal CG up until 4th of July weekend, but it all depends on their assessment of road conditions. Therefore, as we said before, if you have a mountain bike(s), you could ride up this road for the 3.25 miles to where the climb for Petroleum Peak begins. This could save considerable time, especially on the return trip. The road, last time we were on it was in generally good condition and not too rugged. Drive, ride or walk this road to these coordinates, where an old jeep track heads off SW for Anderson Lake. N 39° 01' 51.35" W 106° 36' 54.99" Elev. 11,225

    Route Description

    Year Climbed: 1990

    Note that both the mileage and elevation gain estimates are based on starting from the Portal Campground. If you have 4WD or mountain bikes, you can eliminate 3.25 miles of walking by driving/biking south up the road. See the "Approach" for details.

    From the coordinates provided in the "approach," follow the 4WD track down to the creek and wade across. Continue up the track as it heads into the trees and tends SW toward Anderson Lake. Follow the track/trail to Anderson Lake, which sits above tree line. From the lake, head towards Pt.13,105 which is NNW of the summit. You can walk on mostly grassy/tundra slopes to the point. The first 700 feet in gain is not too steep. The next 500 feet in gain becomes quite a bit steeper.

    Once you gain Pt. 13,105, walk south following the ridge crest. About a third of a mile south, the ridge will begin to turn to the SE and then east for the final section to the summit of Anderson. Much of the ridge walk is tundra with a mix of rock conditions like embedded rocks, talus & rubble at times, but nothing very difficult is ever encountered. There are great views to be enjoyed from this summit in the heart of the Sawatch, especially to the west where you should be able to make out some of the Elk Mountain summits. Descend as you came. There is a report on LoJ that it's possible to descend a scree or snow-filled gully (depending on the time of the year) to the NNE that terminates near Anderson Lake. Early season climbers could find an ice axe useful for sections of this route.
