A barbed wire fence will be on your right. Go 0.5 mile down the road to cross the creek, coming to a flat, sagey meadow. Go right on the main track, marked by a signpost "115" and signs, "designated route." Climb on the dirt road. Good 4WD vehicles could make it to here. Cross two small ridges. The road continues, switchbacking up to a large plateau. Patterson is the light colored massif straight ahead to the east. Follow the jeep track to the vicinity of the top.
