Originally bolted in 1990 an extension with a second seperate set of anchors was added in 2002. Long, sustained and powerful this route requires good core strength and the ability to pull down hard with good technique. Starting on a short slabby ramp to steep overhanging terrain on good flakes, crimpers and jugs to a short rest at the first set of anchors. Continue on for three more bolts on scary flakes to the second anchor....[more]   Browse More Classics in CA

This was taken in 1984 way above the Voices Wall.   That year I would grab some of my Cross Country buddies and skip practice, drive up to Williamson and get as much climbing in before it got dark.   I taught them how to do a hip belay and we went for it.    Those were some fun times.

Went out there a few days ago. Just went off a guide book and didn't know about the closure. Only one small sign near trailhead mentioned it being closed. We called the forest department and spoke with them. When asked when it might reopen they told us no time soon.

2 more years. I would like to hope the climbing community can band together to put up a legitimate fight this time around.

I wonder if the luminaries who closed this area understood that other crags hereabouts (SoCal) would be adversely impacted? Scientists tend to wear blinkers.

Holcomb Valley Pinnacles comes to mind.

Hooray.....the "proposed" plan is for Williamson Rock to reopen in August 2016, with an open period from August 1 - November 15, under a special Visitor Use Permit System, with limits of 90 visitors and 30 cars/day, and a Forest Service Site Manger with citation authority, on sight during the open season. And monitoring of trespassing activity during the seasonal closure from November 16 - July 31.
Don't expect the Stream Wall, London Wall, Mushroom Boulder, Stash Slab, Little Tokyo or other stream-based rock routes to be accessible, as the plan is for signage and barriers to be installed to restrict access to these popular areas. But there will be a vault toilet installed.
