Directions

The following directions describe an approach to access the peak's north ridge. From Norwood, drive east on State Hwy 145 1.4 miles, turning south onto County Road 44ZS (signed as Lone Cone Road). Continue south on 44ZS for 11. 6 miles, turning east onto County Road M44 (Beef Trail Road). Proceed for approximately 2.4 miles then turn south onto County Road 46M. Travel south for 5 miles (road becomes Forest Road #611) to the intersection with Forest Road #615 . Follow Forest Road #615 for 1.6 miles, then turn west on Forest Road #612 . Continue on #612 for 3.8 miles, passing Forest Road #612.1b to a closed road on your left. (Forest Road #612.1b is a good dispersed camping location but not recommended for peak access). Park at the vehicle barrier (at coordinates N3754.390' W10814.488'). Walk generally south then southwest along a closed road, reaching a small pond in 0.3 mile. From the pond, climb steeply to the southwest up forested slopes aiming for a saddle on the peak's northeast ridge labeled as an 11,230 foot contour on the USGS topography map. Once on the ridge, join a faint trail and walk southwest up the ridge crest to tree line at 11, 500 feet (approximately 1.1 miles from your vehicle). This is where you leave the northeast ridge. Contour west and scramble 50 feet up a steep, loose scree slope to gain the rock glacier which separates the northeast and north ridges. Contour across the rock glacier which forms the seat of the feature known as the Devil's Chair. Aim for tree line on the north ridge and pick up a climbers' trail that ascends to the crest of the north ridge at 1.6 miles. Follow this trail south up the ridge until it disappears among the talus. Continue south and then southeast to the summit. A high clearance 4-wheel drive vehicle is recommended. For climber's wishing to climb the northwest ridge: Portions of County Road 40J (west of the peak) are closed to public access.
