Punk Rock primarily offers bolted slab climbs ranging from 5.7 (ish) to 5.12. There appear to be several newer and easier climbs located on the far right side of the dome that are not in the Sequoia Kings Canyon Guide. The back side of the dome (facing Penstemon) has several easier crack climbs ranging from 5.5 to 5.7.
At the "Y" take a right and head to the end of the paved road. This is the Maxon Parking lot. From the parking lot, you will see the dome on your right. The closest climbs are about 5 minutes from the car.
