Boulder with a couple lines on it, couldn't find that it was on here already. One of the lines, "Classic Arete" was featured in Friction Addiction.
Once up at Old Baldy, look for the highball scarefest Strongbad V7, this boulder is to the right and behind that problem. It is south of the Crimp Ladder and Buffalo boulders by a couple hundred yards.
