This route lies just a little left of the actual slab routes at Swan Slab. I don't know what the real name is, since it's not listed anywhere, but it runs straight up and left to an Oak tree.
It is a nice short boulder/solo or TR.
Walk to the slab routes and go left along the base. The first easy crack you come to is Oak Tree Crack. You top out on the big open slab where the park service takes kids for the kid meeting things they do all the time.
Fingers pieces or so. This route is best TR'ed via the Oak tree, or just soloed. Webbing for anchor, usual TR stuff, or a pad.
