Boulder with climbs 12-20 feet high located on property owned by Pacific Union College, currently accessible to the public. Located within forest, thus shady throughout the day. Mosquitoes are bad during spring and early summer. Although most climbs are usually bouldered, all can be top-roped from tree anchors in combination with rusty bolt anchors for a directional (double bolts with a chain above main south face, single hangerless bolts on each end). Names of climbs are given as a convenience for the climbing community, but if anybody knows of earlier names (or objects to new names coined for old problems), I would happily rename (or delete) them.
From the junction of Silverado Trail and Deer Park Road in St. Helena, drive 5.4 miles north on Deer Park Road, which eventually becomes Howell Mountain Road, to the campus of Pacific Union College. Turn right on Cold Springs Road and, after 0.2 mile, continue straight across an intersection onto Las Posadas Road (Cold Springs Road turns right) for another 0.9 mile to a 90-degree bend in the road. Park at the bend of the road and hike on the trail that proceeds east (the same direction you were just driving). After about 0.1 mile you cross a fence and a dirt road, then reach a fork after another 0.1 mile. Stay right at the fork and continue about 0.4 mile until you see Mossy Rock on the left.
