Description

This very round dome is found behind the Freak Brothers Dome and is home to a few moderate face routes as well as Dihedron (5.14a), the hardest traditional route in Joshua Tree. Perhaps not a destination crag but a good place to escape the crowds.

Getting There

Head into the Wonderland as if for the Freak Brothers. About 100 yards past that, turn right up and into the valley. The large Disneyland Dome is on the left, while this is on the right, forming a corridor between it and Fat Freddie's Cat.
