PB is a small block just off the trail, 15 minutes from the trailhead. Several boulder problems are listed in the Horan guide. PB seemed excessively covered in lichen, rather small, and not particularly appealing.
From the dumpster below Saxon Rock, follow Saxon road to the trailhead in the neighborhood. The Saxon Road continues right, switching back and forth up Saxon Mountain. The trailhead to PB is unmarked but just adjacent to the last house and down a small incline.
