Peak 10201 is located on the east side of Mammoth Canyon and is northeast of the main White Knob Crest. It is most easily climbed from FSR-517/Mammoth Canyon Road and the northwest ridge. The book’s commentary is a bit misleading, as discussed below. USGS Shelly Mountain
Access
From the junction of Main Street and US-93 in Mackay, drive 2.4 miles south on US-93 to a signed junction with Houston Road. Turn right/south onto Houston Road and drive 2.0 miles to an unsigned junction with Alder Creek Road. Turn right/south onto Alder Creek Road and drive 1.6 miles to an unsigned junction at a private ranch and a sharp right/southwest turn in the road. Reset your odometer here. From the unsigned junction, drive southwest on Alder Creek Road.
At 2.9 miles, reach the Challis National Forest boundary. At 7.7 miles, reach a signed junction. Go straight/northwest onto FSR-517/Mammoth Canyon Road. FSR-517 is narrower, rockier, and more rutted than Alder Creek Road, so drive up it slowly. A 4WD vehicle with good tires is required but high clearance is not necessary. Drive 0.8 miles up Mammoth Canyon Road to a signed junction with FSR-516/Stewart Canyon Road. Park at this junction (8,310 feet). From here, FSR-517/Mammoth Canyon Road is a narrow jeep road with some rocky sections and would require an ATV or a high-clearance 4WD jeep with good tires.
Southwest Face/Northwest Ridge, Class 2
The Climb
From the road junction, hike (or drive) about 1.3 miles up Mammoth Canyon Road and reach a large clearing on the right/northeast side of the road at about 8,890 feet. Leave the road and scramble diagonally left/north to skirt the left/west side of a rocky buttress in open scrub and tree stumps. After passing the buttress, bushwhack straight/northeast up the forested slope to reach the crest of the northwest ridge at a minor saddle (9,780 feet).
This is a steep scramble up through an open forest of aspens and short pines with a loose gravel/sand base. You will find diagonal elk trails in the soft, loose terrain to expedite this climb. Once on the ridge, go right and scramble east-southeast up the ridge crest to the rocky summit outcrop. The ridge terrain is a combination of embedded boulders and short scrub with a few minor rocky outcrops and talus/scree patches. The summit high point is a large boulder. There is a small summit cairn nearby.
It might be tempting to shorten this climb by scrambling up the southeast ridge instead. However, based on what I saw from the summit, the southeast ridge has a major collection of difficult ridge towers at a complicated ridge point southeast of the true summit. It would be difficult to navigate through or around these ridge towers, so I would avoid the southeast ridge as a potential route of ascent or descent.
You can continue hiking up Mammoth Canyon Road all the way to near the Mammoth Site and then scramble a short distance in open terrain up onto the northwest ridge. From there, head southeast on the ridge crest and navigate a few rocky ridge points to intercept the ridge entry point described under the Southwest Face/Northwest Ridge Route earlier.
