Fun, but not V4... using The Pearl in Red Rocks as a baseline. Too bad user chirp said the pockets were drilled; i had a feeling they were. Not sure you're allowed to boulder in Zion, as that was the only boulder with chalk marks on it I saw... then again, I just stayed in the valley doing short day hikes. I parked in the South Campground parking lot by the Nature station. It is right across the street from the Bunnyhop boulder.
