Upstream from Castle Rock, cross the log jam, head up hill then bear right along the cliff band, maybe 50 yards, then head back towards the creek a bit. The problem starts under the egg shaped boulder. Pull over the lip, mantle and top out.
Got on this one today. It was a lot of fun. I could not figure the beta to get my body over the lip yet. Seems there may be a few good ways to do this one, but I just could never make total since of the moves to get one's self mounted up on the up part of the wall!!? Just day one though.... hopefully a few more visits and I will send.
F.Y.I. I a decent place to cross to river that is close to the problem. It's a log jam that was ok to cross and made access much easier. But as usual be careful if you walk the logs as I did... you could take a spill of even get hurt!!!
