Overview
Organ Mountain is a high 13er just east of San Luis Peak in a remote part of the La Garita Mountains. Rock pillars on one side of the summit look like organ pipes. Organ Mountain, Baldy Alto, nearby Stewart Peak and San Luis Peak all make sense from one short backpack trip up Stewart Creek.
This is best done as a backpack. You hike about 5 miles up the Stewart Creek trail to a camp on the South Fork, then climb the northwest ridge on grass, tundra and rock set in the ground, cut over to the saddle north of the summit, and finish on bigger boulders. It is Class 2 with no exposure. Kids of 10 and 12 have done it from camp.
The round trip is about 12.6 miles with 3,335 feet of gain from the trailhead. From camp, the summit is about 1.3 miles and 1,685 feet up.
Plan of the day
Leave camp by 6:30 a.m.
Be at the saddle north of the summit by 10:30 a.m.
Boulders on the last stretch.
Easy. Leave the northwest ridge before Point 13,540 and aim for the saddle north of the summit.
Stewart Creek and its south fork. Filter it.
Getting to the trailhead
Stewart Creek
Take Highway 114 south from US 50, about 7.5 miles east of Gunnison. Drive 20 miles and turn right on NN14 (BLM 3083). From Saguache over North Pass, this turn is about 7.5 miles below the pass. Follow good gravel about 7 miles to the south end of the Dome Lakes and turn right. Reset your odometer here.
This road is County Road 2166 (also signed 15GG or BLM 3086). It loops around the lake and runs north along its west side for about a mile; turn left to stay on 2166. Keep right at about 4.2 miles, where it becomes 14DD. Between miles 6 and 7 you enter national forest, the road becomes Forest Road 794, and it gets rougher. Stay on 794 to the Stewart Creek trailhead, just under 21 miles from Dome Lakes. Older books send you by Forest Roads 788 and 790; this way is quicker and simpler.
All told it's close to 30 miles of dirt. Some cars make it, but rain can rut the road, so a crossover or anything with more clearance is the better choice. There is a little camping at the trailhead and a larger area a short way east down the road at the next sharp right bend. The Eddiesville trailhead, with a toilet, is about half a mile east.
