The Birthday Boulder is a 20 foot high slabby rock with a few horizontal cracks. It is located on the south side of the Caesarian Tower. The boulder offers a range of difficulties depending on how you climb it. You can link the Birthday Boulder up with the two routes above it (Caesarian Tower or Special Delivery) for a nice 50 foot climb. Special Delivery is a little overgrown. The tree on the right could use a haircut.
