Although this problem has some pretty horrendous rock the moves are actually quite good. With more traffic it could clean up enough to warrant a star.

Start with hands matched on a slanting lichen-covered rail, run your feet up high and mantle up with tricky balance moves and loose grains.

This problem isn't listed in the Joshua Tree Bouldering Guide but is an obvious line with some good moves that may or may not be worth a go when in the area.

Unspeakable

Unmentionable

SDS at a jug and make easy moves out an overhanging rail to an awkward lip encounter with good hands and undercut feet. Once established past the crux easy moves up the slab gain the top of the boulder.

A good spot is recommended on this problem to keep you off a rock directly below the crux.
