Approach
Shephard Pass trail ( arguably worse than the climb ) to a camp in Williamson Bowl.
Route Description
We followed the drainage east from Williamson Bowl below the North Face of Mt. Williamson to around 11,000', contouring up and East to the Rib. We crossed the Rib and climbed the Rib primarily on its East side. Lots and lots of 3rd class lead to a huge tower which is climbed on the left side. Eventually the walls close in from the left and one is wise to rope up for the last bit. About 3 pitches of class 4 - easy 5 lead to a notch, followed by one more pitch to the top of the West Horn. From here, follow the West Horn description in the Secor guide. Enjoyable, long, recomended.
Essential Gear
A small rack, slings, rope, lots of water!
