Greasefire Boulder

Greasefire Boulder is a bouldering area in California's Mount San Jacinto State Park, within the San Jacinto Ranger District of San Bernardino National Forest. The land is managed by State Park and Recreation, and the boulders sit among several other climbing areas, including Gold Crack Boulder/Which Way Jose and Area 51/Deer Canyon, both about 0.1 mile away. The area has six boulder problems, all rated from V2 to V6 on the V scale. The hardest is Greasefire, a V6 boulder with a first ascent by Andy Blair, and the Right Variation and Imperfect Circle are both V5. The rest sit at V2 and V3, so climbers can find routes to suit a range of skill levels. The Round Valley Trail and Desert View Trail are both within a mile, and Black Mountain (San Bernardino) and Fern Basin campgrounds are about 5 miles away.
