When I was in high school, we always called this "Indian Rock"...
BTW, The rangers used to only make one or two patrols around sunset to hand out tickets to people that park there, they never come around later at night, since none of us ever got tickets for drinking beer and stuff out there on weekend nights.
Route Climbed: Unknown 5.8 Date Climbed: Feb / March 2005
Rock Climbing the San Francisco Bay Area rates this a 5.8 or 5.10b slab route, depending on whether or not you aid on the tree for the first 10 feet (Rock Climber's Guide to Skyline Boulevard calls it 5.9).
Well, Matthew and I aided on the tree ... a fun local winter climb to train for friction. Setting up a TR just requires a little class 4 but is otherwise pretty easy.
