This easily accessable, small crag is well worth a visit if you're in the nieghborhood. You'll probably have this peaceful place all to yourself. All the routes but one are on the northeast side, so count on being in the shade most of the time. The rock is typical Big Bear granite, some very good and some a little gritty and licheny. The routes are about 40-50 ft. long. While none are mega-classics, all of them provide fun and interesting climbing.
Getting There
About two miles down the hill from the top of Cushenberry Grade (towards Lucerne Valley) on the east side of Hwy 18 is Forest Service Road 3N62. The new (2008) Brad Singer guide book says to take the next road just downhill from here, but as of Sept '08 this was blocked off with a no trespassing sign. Instead, take F.S. Road 3N62 itself for about a half mile, bearing right whenever the road forks. Blackhawk Pinnacle will soon be seen off to the right a short way from the road. Another possible approach would to take a different dirt road off Hwy 18 about a quarter mile back up the hill from F.S. Road 3N62. A straight drive east will take you near the other (south) side of the crag.

As noted in the description this is at best a diversion if driving past, and would be hard to recommend to anyone as a destination. Good bouldering exists in the area and is much more worthy of a stop.
