  • Trailhead
    • Cunningham Creek - Silverton Trailhead

      From the Town of Silverton, drive to the east end of town where the paved road splits one block past the courthouse. Set your odometer and veer right onto blue-signed County Road 2. (On Trails Illustrated map #141 this is road #110 aka: BLM 4500.) After 2 miles, the pavement ends and the road becomes well-maintained, graded dirt.  At 4.2 miles, you'll come to an intersection and the old townsite of Howardsville.  Turn right onto BLM 4513 or FS589. A sign here indicates Cunningham Gulch and Stony Pass. At 4.4 miles from town, stay right. At 5.9 miles, stay right again. Do not drive up the Stony Pass Road. Continue driving south along Cunningham Creek. At about 7.1 miles is the place to park to access Little Giant Peak. At 7.6 miles is an old toilet on the east side of the road and a camp area on the west. At 7.8 miles, the good road ends, but passenger cars with moderate clearance can still make it to the trailhead. Take the right fork, drop down and cross the creek, then begin climbing on a single switchback to the trailhead. At 8.6 miles, turn left and descend sharply to cross Cunningham Creek again, (This is a low-water crossing which can be difficult in runoff season,) then drive another .2 to the limited trailhead parking area. If there's no room to park here, you can park before crossing the creek on a flat area just beyond the intersection atop some old mine tailings. Trailhead coordinates provided above are for parking at the first crossing of Cunningham Creek.  The coordinates for the actual trailhead are: N 37° 46' 51.43" W 107° 34' 47.30".


      Camping

      At either of the two trailheads, you could park and vehicle camp overnight. On the drive up Cunningham Creek, once you pass the turnoff for Stony Pass, you can find a few other pullout type spots for an overnighter. Be careful about private property issues though. Back along CO110, there are a number of at-large, primitive sites, usually occupied by RV's and the likes. The nearest National Forest campgrounds will be either up South Mineral Creek or Little Molas Lake.

      If you desire to spend more than a day in the area of the Highland Mary Lakes, then there is a short little backpack you can do to a good camp location that's only about 1.5 miles in from the passenger car trailhead or about 1mile from the 4WD trailhead. It's located in the last trees north of the lakes just above 11,670 ft., on a sloping ridge between the two main forks of the creek. There's room for several tents and a good water supply. This is where the trail to the lakes takes a decided turn to the west to follow a secondary drainage. Coordinates are approximately: N 37° 46' 10.4"   W 107° 34' 34.8".

    Route Description

    Year Climbed: 1997

    Note: Our route description for Mountaineer Peak takes you over another lower-ranked 13 called Mt. Rhoda. Both the trailhead and route descriptions for these two summits will be largely the same.

    From the passenger car parking at 10,460 ft., hike along the road as it crosses to the west side of Cunningham Creek and then heads uphill and south. In a little over a half mile, you'll arrive at the 4WD parking and the end of the road which again crosses back over Cunningham Creek. A gate prevents further driving, but the vehicle track continues some distance before becoming more of a trail. Not far up from the upper trailhead parking, the creek passes through a narrow chasm of either granite or metamorphic rock and presents quite a tumultuous sight. At about 11,620 feet, will be the campsite we mention in the trailhead description. It's on the slope of a hillside that runs between the two major forks of Cunningham Creek. On this unlikely looking slope, there are some tall trees and some flat spots to pitch a tent.

    The main trail to Highland Mary Lakes turns west here crossing and following the stream, then turns south again to follow the main stream that drains one of the first lakes. A few hundred yards before arriving at that first lake (12,100 ft), cut right (west) up a steeper slope and gain the south flank of a mostly tundra-covered, broad ridge that's east of the Mt. Rhoda summit (UN13,402). Follow the ridge west and contour into a basin on the south side. Stroll on up the lush basin admiring the wildflowers (if you're there at the right time) and at the head of the basin, either hike up the SE flank of Mt. Rhoda or walk to the saddle south of the summit. Since this little summit poses no difficulty other than a very minor cliff band near the summit, it's just as easy to hike over it as around it. If you go to the south saddle, you may wish to contemplate hiking south first to Whitehead Peak (unranked), and then on to UN13,109, before turning around and going to Mountaineer Peak by way of Mt. Rhoda.

    From Mt. Rhoda, it's an easy hike across to Mountaineer Peak (UN13,434). There will be some scree and rock mixed with plenty of tundra and the hike over should take under a half hour. The views from any of these summits allows you a panorama of the Grenadier Range to the south, with Arrow and Vestal Peaks standing out prominently.

    To descend, you might want to consider an alternative route back. Drop south along the ridge from Mountaineer Peak to the saddle, then descend into the basin to the east. (Spencer Basin) Head ENE across the basin to a ridge and saddle just SW of "Sugarloaf." Cross the ridge, descend on scree and tundra into the basin below and in another half mile, pick up the Highland Mary Lakes trail to finish out your day. When we hiked in Spencer Basin, it was a 4th of July weekend and most of the basin was still filled with snow. We suspect much of the basin, once you're off the peaks, is tundra and grass. If you like to play around in the snow, then this entire area is good for earlier summer season access.
