A massive 45' tall boulder that's cracked in half (hence the name). This is one of the best places in the Bay Area to take beginners or kids, though the holds on the West Face are quite rounded making for insecure climbing which may baffle those new to the sport - the South Face may be a better introduction for raw beginners.

Bring a solid rack up to 3' and a lot of long slings (or better yet, a second rope), as the protection for the top-rope anchors is a long way back from the edge.

From the parking lot at the end of Taylor Rd the boulder is obvious, straight ahead.
