Huerfano is a Centennial Peak which can be done on its own, or added on to a trip up Mt. Lindsey. If done in combination with Lindsey, the trail to Huerfano adds 1.5 miles and 700 feet of elevation. The Iron Nipple can be easily added into this route adding in a few hundred feet of Class 2 vertical.
The trail up to the Lindsey/Iron Nipple saddle is very well defined, but after the saddle it doesn't have a defined trail or cairns, though it is easy to follow. You may find scattered light trail sections, but don't expect them for long.
From the trail-head follow Bill Middlebrook's excellent route description for Mt. Lindsey's Northwest Gully until the Mt. Lindsey/Iron Nipple saddle at 13,150'
Shows the route from just near the Lindsey/Iron Nipple saddle. From the saddle, turn north (away from Lindsey) and hike toward the Iron Nipple. Once the terrain starts to raise look for a large V-notch with flat sides. The easiest way up to the notch is on the left side, as seen in 2
. After the V-notch you will reach a small saddle where you will turn slightly right and descend about 50 feet following the large cliffs of the Iron Nipple 3
Hug the large cliffs and you will see a talus field in front of you 4
. There is no set trail up the talus, but do a rising traverse aiming for where the talus ends near the grassy ridge. From here point uphill and pick your line up the ridge to the summit. Follow the line of least resistance which doesn't necessarily follow the official ridge. The summit is obvious and provides amazing views.
