Description

This is the rock behind the rock behind Pathetic Dome. As you approach Pathetic Dome from the road, walk around it on the left side. The next rock is the Prime Clump; keep walking, and next the Nuclear Reactor Rock should come into view. Look for a hand crack that eventually peters out a short distance below a bolt (that's "Cunning Linguist," also known as "We'll Get Them Little Pricks").

Getting There

Walk across the street from the Jumbo Rocks campground. Keep walking, bear slightly left, look for an obvious dome with an obvious offwidth/chimney splitting it up the middle. It's kind of hard to miss.
