A high concentration of moderate boulder problems are clustered around the South Parking area, Classic Rock among them. This is a good warm up area (or destination unto itself for moderate boulderers like myself) for the more serious routes that abound.
The rock is a square-shaped, tall boulder that leans to the north, the overhanging side the home of its namesake route "Classic Crack". Climbing options circle its girth.
This rock sees less traffic than the "star catchers" nearby, perhaps because of the aggressive and annoying vegetation that guard the rock.
Getting There
Once you've located the Book Rock (above the Scenic Boulder, which is clearly visible from the parking lot. Or at least the chalk on Scenic Boulder is visible) take the rocky path leading northwest from the open book. A thuggish square boulder looms on the right. Follow the path around the north side to find Classic Crack hidden among the brambles.
