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.

Northeast Ridge, Class 2
From the parking pullout, hike south up a spur road for a short distance to intercept [unsigned] Sawmill Canyon Road/FSR-069. Follow FSR-069 right/west. Stay right at an unsigned junction with a spur road that heads left/south. Leave FSR-069 soon after it exits the forest. Scramble left/south up a steep-ish sagebrush slope (with some scattered pines) to reach the crest of the northeast ridge. You must cross a stiff, high cattle fence early on.
Follow the meandering ridge southwest then south then southwest to reach the elongated, narrow ridge crest summit of Peak 8571. The northeast ridge is a combination of scrub, a patch of thick pines (with lots of blowdown), and a rocky section near the summit. The high point sits back (to the southwest) of the “summit” hump that you see as you climb the ridge. The summit has a modest cairn.
