I'm not even sure if this is the right name for the crag. There are maybe six bolted routes on slightly overhung edgy rock. Routes are generally in the 5.11 to 5.12- range. It is on the Mt. Persis approach road just before index. Very solid rock, and very well bolted pumpy routes.
There are some boulers right next to the clif that would likely have some good problems if they were scrubbed.
From Highway 2 heading east, take road 62 (maybe 5 miles before the index turn off), go up this until it levels out(maybe 3 miles). Look for an obvious road on the right side. The crag is hidden in the trees a couple hundred yards on the right side down this road. You will know you are close if you see a ton of shotgun shells.
