Flintstone Rock can be a great place for lunch if you're climbing in the Pine Cliffs area, as you can often find shelter from the blistering east bay sun under it's large overhang. Because of the fragile nature of this rock, bring long slings for topropes(20'+), don't climb this area for at least 3 days after a rain storm, and be careful of loose bolts and anchors, as many of them cannot withstand too many serious falls. The rock itself offers a variety of climbing, despite the fact that presently only two climbs have been developed on it. Yabba Dabba Dudes (5.10a) is on a very chossy face that is on a large portion of rock that has cracked off the main cliff. The chimney climb that ascends this crack is the other route, Pigeon Tunnel. To the left of these two routes is an enormous overhung cave with tons of features. I would assume that the difficulty of top-roping this area has served as a barrier against further development.
