The Pettijohn Trail starts at Stuart Gap Trailhead and follows up a gentle ridge to the wilderness boundary and then drops on to the edge of Pettijohn Basin. Then on to the top of the ridge through a short-steep series of switchbacks. At the top of the ridge there is a junction with #10W60 (Black Rock Mountain Trail), also a good view of the wilderness to the west, North Yolla Bolly Mountain to the southeast, and Mt. Shasta to the north. The trail then drops down through Cedar Basin to the southeast and it's junction with #9W36 (Humboldt Trail) where it ends. There is good water in Pettijohn and Cedar Basins.
