Peak Summary

From Williams South B (13,203), a long ridge traverse with Class 2+ problems to overcome, or from Williams South C (13,033) a fairly easy Class 2 ridge walk. Trailhead is accessible by passenger car. This summit may be part of one very long day cleaning out the entire Williams group or part of a two or three day backpack that can net a half dozen 13ers.

  • Trailhead
    • Lost Man Trailhead

      The name for trail #1996 is "The Lost Man" trail. It has two access points off Highway 82 out of Aspen. The first access is 14 miles east of Aspen and is a large parking area on the north side of the highway, across from the Lost Man Campground. This section of the trail leads up to South Fork Pass and Lost Man Lake. If accessing the Williams Mountains, this is the shortest and easiest access. Once across South Fork Pass, the trail number changes to 1940.

      If coming from the Front Range, turn west off onto SH82 from US24 between Leadville and Buena Vista and drive past the Twin Lakes Reservoirs, through the small town of Twin Lakes and continue west up to the summit of Independence Pass. From the summit, continue driving west. At the first switchback heading down is what we are calling the "Roaring Fork River" trailhead. This is actually the other end of the Lost Man trail #1996. Drive on west past here, for another 4.3 miles to the Lost Man Campground and parking for the Lost Man trail on the north side of the highway. The parking lot is sizable.


      Camping

      On the west side of Independence Pass, at-large camping opportunities have all but been taken away. There are four designated, fee-type national forest campgrounds however beginning with Difficult Creek (four miles out of Aspen), Weller, Lincoln Gulch and Lost Man. All of these tend to fill on weekends. It may be possible to stay overnight in your vehicle at the Lost Man trailhead parking. Do this at your own risk of being run off.

      • Lost Man Trail Approach  Easy | RT: 9 mi / 1,300’

        This approach information is provided for those who would want to backpack in as far as South Fork Pass or beyond in order to climb the four Williams summits and possibly some other unnamed summits NE of the Williams group.

        From the Lost Man trailhead, hike north to Lost Man Reservoir which is about one half mile in, gaining about 200 feet elevation. Before reaching the reservoir, a little over .3 mile from the TH, another trail turns off to the left. This is Forest Service trail #1993 to Midway Pass. Use this trail to climb UN13,033 (Williams South C) or if you want to attempt a traverse of all the Williams summits from the south. Otherwise, continue north from the reservoir on the Lost Man trail for about 4.5 miles total to South Fork Pass at 11,840 ft. The trail is fairly level most of the distance, with the steepest elevation gain just prior to the pass. At about 2.4 miles up the trail, or about .4 mile past the crossing of Jack Creek is a possible campsite that lies on the east side of the trail and overlooks a section of the creek that enters a shallow, rocky gorge. The campsite is not far off the trail. Try these coordinates: N 39° 09' 02.60" W 106° 36' 37.41". However, most would probably prefer to get further up the trail before camping. Overall, there was a lack of viable campsites along this trail all the way up to the pass.

        Before reaching South Fork Pass, the Lost Man trail actually turns off to the east to go up to Lost Man Lake. If interested in climbing the lowest 13er in the state, you could turn off here and hike up toward Lost Man Lake to ascend the peak. Otherwise, where the Lost Man trail turns off to the east, continue north to South Fork Pass, now just a short distance away. At the pass, if you explore over to the west of the trail, there's a very small pond with some camping possibilities at these coordinates: N 39° 10' 20.21' W 106° 35' 33.53". If you do not wish to camp here, this is the location that we used to launch off for UN13,203 (Williams South B) and also Williams Benchmark (13,312).

        For Williams Mountain and UN13,108 (Williams North), continue packing north, down the trail now for about another .7 mile to a third possible campsite in the vicinity of these coordinates: N 39° 10' 44.21" W 106° 35' 01.91". This is only a very rough estimate of where we camped. The so-called campsite we used was on the west side of the trail and barely off the trail and overlooked the creek. On the east side of the trail, if you wandered up over some rock outcrops, there was evidence of a couple of other marginally used spots. This mad a good location to launch off for Williams Mountain and Un13,108 (Williams North). If you access them the way we did, you will need to continue down the trail to Deadman Lake. The terrain around Deadman Lake we found to be rather flat and wet, but there may be a viable campsite around there.

      • Williams Benchmark NE Ridge  Class 2+ / 1.25 mi / 850’ One-Way


        This route description picks up from the summit of Williams South B (13,203). Begin by heading along the ridge south from the summit of Williams South B. Some may wish to attempt a direct line across the ridge. Foreseeing some problems with that, we chose to drop down off the ridge a few hundred feet on the east side to avoid the problems and then re-ascend to the false summit at 13,180 ft. Continue heading SW now along the ridge crest on rocky and slow terrain. Before reaching the lowest point of the connecting ridge between the two summits, you'll encounter some more difficult obstructions. Again, you may attempt to either stay on the ridge crest or do as we did and drop off to the south side to avoid them. If you drop down, lose about 200 feet and then contour SW below the cliffs and continue until you come to tundra slopes that will help you regain the ridge. You'll have to contour across a rocky boulder field at one point. Once back on the ridge, it's easier walking to the summit, partly on tundra to begin with, then finishing on rubble.

        For the return trip, head south from the summit a little and then turn east and drop into the tundra basin below. Don't drop too low so you can contour across the east running ridge off the unranked summit of 13,180 ft. Once on that ridge, you can either drop down into the next basin north or just follow the widening ridge, staying on open, flowering slopes all the way back down to South Fork Pass.
