Description Suggest change

This rock is entered here to provide organizational clarity. This crag is located in the cluster of rocks known as Jurassic Park. According to Rick Thompson, this rock located just downhill from the Dinosaur's Foot is known as "Big Ass Slab." Perhaps, there is a more tactful name (especially for little kids climbing here) for this rock?

On this slab are at least 4 established lines and possibly more. Clean, low-angle rock with primarily bolt protection is probably the best way to describe this crag. Nonetheless, this rock is still fun to climb.

Getting There Suggest change

Hike up from Lily Lake on the established ridge trail that switchbacks a short distance from the parking lot. Angle uphill towards the obvious rock and find the climber's trail. If you reach Dinosaur Rock or The Fin, you've gone too far. The 4 obvious routes start virtually on the climber's trail.
