A difficult to access peak in a remote location requiring 4WD and a lot of driving, but the peak itself is easy Class 1 to Class 2 hiking and can easily be combined with two other 13er summits for a 3 peak day.
WARNING: This trail head approach REQUIRES 4WD with good ground clearance. The drive as described below from Silverton may take up to 2.5 hours.
From the Town of Silverton, and where the main road splits at the NE end of town, drive 4.2 miles NE up along the Animas River on blue-signed County Road 2 to Howardsville. Turn right onto FR589 up Cunningham Gulch and stay right at the turn for the "Old Mine Tour" (4.4 miles) but do take the left fork toward Stony Pass (FR737) at 5.9miles. Once on the Stony Pass Road, expect 4W conditions. The road climbs steeply to the pass. Abundant wildflowers as you approach the pass may delay you. Once across the pass, the road becomes FR520 and eventually leads to Rio Grande Reservoir, but you will not drive that far. The road eventually descends down the valley to a low water crossing of Pole Creek. Watch out for the steep embankment climb out on the other side if the road is wet from rains. You could easily slip off the edge. After the crossing, continue south for about a mile to another fork where you'll turn right (west). Another long, low water crossing is found here across the Rio Grande River. This crossing is usually more shallow than the Pole Creek, but the closer you are to runoff season, the more difficult these crossings will be.
It is also possible to come into this area from either Creede or Lake City over Slumgullion and Spring Pass to Rio Grande Reservoir. From state highway 149 either about 20.5 miles from Creede or 32 miles from Lake City, turn west onto FS520 and drive all the way to the reservoir on the well-signed, graded dirt road. Passenger cars can make it all the way to the "Lost Trail Campground" at the far west end of the reservoir. Beyond that point, FR520 continues west and crosses some rugged sections before connecting with the other section of FR520 coming down from Stony Pass and the low-water crossing of the Rio Grande. We have never driven in all the way on this section and from those we know who have, they have complained about one particularly difficult stretch.
From the Rio Grande crossing, continue up what is now, the Beartown Road for a slow 7 miles (mainly because of potholes). The road goes all the way to Kite Lake at about 12,100 ft., but the Hunchback Pass trailhead is about 1/2 mile below the lake. There's a trail sign there and some very limited parking is available. Note: There was a fairly difficult section of road around the Beartown site due to muddy potholes.
As the road begins climbing more steeply toward Kite Lake and the Hunchback trailhead, it becomes quite a bit more rocky in that stretch as well. If you have driven in here to do the Ute Ridge group of summits, camp in the vicinity of where the road crosses Bear Creek just past the old Beartown site. See coordinates below. From that creek crossing, it's not quite .3 mile to the trailhead for Ute Ridge, which is a jeep track that turns off to the left and drops down to cross another lesser fork of Bear Creek. Park somewhere along this track if heading for Ute Ridge. On the Caltopo map, this trail is called the "Bear Town Trail" and designated FR869. On trails Illustrated Map #140, it does not appear to have a designation. Coordinates for this road & trailhead are: N 37° 42' 54.53" W 107° 30' 35.00"
You can find some very limited camping spots in the immediate vicinity of the Hunchback trail head. There's one particularly good spot back down the road a fairly short distance on the south side. There's also some good camping back toward the Beartown site. See coordinates provided.
From the trailhead described, follow the Bear Town Trail east in the direction of Indian Ridge. Though the USGS map does not show them, there are a couple of switchbacks as you work your way through forest to the open ridge. The first 400 feet of gain are the steepest, then the grade begins to lessen as you approach the tundra and grass-covered, broad ridge. There is a good possibility of seeing elk in this area. We encountered a nice-sized herd when we did this trip and even played a little hide-and-seek with a young bull elk, getting within about 50 yards of him before he bolted and headed for the willows. Be on the lookout. They'll probably spot you before you see them.
Once on Indian Ridge, the trail turns almost south and follows along the eastern flank of UN13,308 and well below its north ridge. The trail then heads for a pass between UN13,308 and UN 13,342. The hiking is on mostly tundra with some scree & rock as you approach the pass. You may be tempted to angle right and depart the trail in favor of a more direct approach to the east ridge of the peak. We succumbed to this temptation by heading up a steep gully cutting through the rocky cliffs below the east ridge. What we found was difficult loose gravel and rock. It wasn't worth the effort and probably saved us no time in the end. Once you gain the saddle, turn right and walk west up the ridge for some more difficult Class 2 work that takes you onto some large, rock blocks. From the trailhead, a good party should be able to make this in 2 hours or under.
From the summit, there are spectacular views to the west and south of the Grenadiers and Needles, particularly the more northern summits. Once you tear yourself away from the impressive sight, either return by the same route or continue on to UN13,342.
From the summit of UN13,308, descend back down the east ridge through the large rock blocks and arrive at the saddle between the two peaks. A hike directly following the west ridge of UN13,432 will get you into some rocky terrain about mid way up but will easily go. If you wish to avoid the difficulty, from the saddle just swing out on the south side of the mountain and do an ascending contour more on the SE flank. Then just head up to the summit on mixed tundra-rock-gravel. Near the summit there are more large rock blocks with gravel in between. This is easy Class 2.
Once you finish your summit visit, either return back to the saddle from whence you came or continue on to the Ute Ridge summit, another easy mile and a half away.
