High quality volcanic breccia featuring lots of pockets. This boulders has a short, over-hanging side and a tall, steep side. The grades here range from V0 to V3 with some tight but OK landings. Not as good as Boulders 1 and 2 but still worth your time.
About 150 yards further up the road from Boulder 1 on the up hill side of the road.
