This peak is the northernmost Sublett Range peak to reach above 7,000 feet. The view from its summit extends all the way across the Snake River Plain to the Pioneer Mountains, the Lost River Range, and the southern Lemhi Range. The name was suggested by Rick Baugher and is based on a rock carving made by Neilsen and Scott in 1898. Rick found the rock on the peak’s slopes (see the photo below). USGS Hartley Peak
This peak can be accessed from the east and ID-34 via Flint Canyon or Hartley Canyon and from the west via Sheep Canyon. I have not driven the east-side roads and will focus on the western access. Please note that Google Maps provides good directions to most points in the Sawtooth National Forest portion of the Sublett Range.
From the east, access the peak from North Heglar Canyon/South Summit Canyon Road/FSR-565. This road is the primary north/south route through the Sublett Range. Both ends of this road are accessed from I-84. To reach the road from the north, leave the freeway at Exit 228. Head east on East Yale Road for 8.7 miles and then turn onto the North Helgar Canyon Road. This road becomes FSR-565 when it reaches the National Forest Boundary. The southern approach leaves I-84 at Exit 245. From the freeway, turn east and follow the road east/southeast into the mountains for 11.0 miles to Sublett Reservoir. This road also becomes FSR-565 when it reaches the National Forest Boundary. Follow FSR-565 to Sheep Canyon Road.
If you are coming from the north, Sheep Canyon Road/FSR-579 is reached at a signed junction 0.2 miles south of the Mill Flat Campground. If you are coming from the south, the road is reached 11.6 miles past the junction of FSR-565 and FSR-564 on the north side of Sublett Reservoir. Please note that although the Forest Service signs this road as Sheep Canyon Road, Google Maps calls it Hartley Summit Road. Turn east onto Sheep Canyon Road and follow it 3.2 miles to the pass on the crest and a 3-way junction. Park here.
South Ridge, Class 2
This route is a pleasant, rolling ridge walk. An ATV trail follows the ridge north from the pass. Follow this track on its up-and-down journey north. When the ATV trail ends, continue north on the ridge crest. You quickly reach an ancient bulldozer cut fire break. Follow this overgrown fire break north. It is amazing how steeply the bulldozer climbed up the steeper sections of the ridge. The ridge is brush-free except for one small section in the last saddle before the summit. The round trip covers 3.8 miles with 439 feet of elevation gain.
