Description 

This is the creatively named 200 foot, west-facing granite slab which is the focal point of the area. Almost all of the routes here are easy to moderate slabs with the odd crack thrown in for variety. Despite the easier ratings the climbs here tend to have an "old school" feel to them and may seem run-out to those unaccustomed to such routes - caveat emptor.

Getting There 

Park in the fee parking area and hike in along a paved service road to reach the obvious west-facing "big rock". Plan on a 10-15 minute approach from the parking area.

The Hard Trough 5.7 5a 15 V+ 13 MVS 4b  CA : Inland Empire : ... : Main Slab
This route climbs the obvious water trough near the far right side of Big Rock. Start up the Puppy Dog-like line of patina and follow the trough to bolted anchors. The first bolt is about 20’ off the deck but you can start the climb on the large flake to the right, traversing up and left to the first clip, for a more comfortable start. There’s a little spice up high, just short of the third bolt, well above the second clip. The sign and the Mayr guide rate this 5.8 but I have always felt it ...[more]   Browse More Classics in CA
