Syzygy

The Slab has many lines but none are too distinctive, especially those like this one in the middle of the face. Hike up the approach trail from the Shanahan Trail. On the approach, look for an odd gnarled tree somewhere in the middle of the summit ridge of the slab. It sits alone and half of it is dead, it's about 20' tall. This tree is a landmark of the route, and (when you can see it) you want to navigate more or less straight at it.

When the trail nears The Slab, hike off left along the base. Very soon you will reach a large, south-facing dihedral, the route begins about about 150 feet south of this dihedral system.

In this area, there is a problematic vertical wall/overhang about 70' up the face, which becomes more significant farther left. The easiest line is not obvious in here, just start up and head right if it is getting too hard (or unprotected) for your tastes.

After you pass this initial steep section, the climbing becomes easier. Head up and left. After about 3 pitches from the ground, you should be able to see the grarled tree. This face is rather indistict and nearly impossible to describe an exact line, just head for the tree. After the tree, head south on the summit ridge. Downclimb off west or continue to the summit (both described in more detail under the route "Diagonal").
