This is a great combination of Pony Express and Zip Code that keeps the grade to 5.9. It includes a wild traverse to link the two pitches. One of the better and longer 5.9 pitches on the West Ridge.
Location
Climb the first pitch of Pony Express up to the small, right-facing corner near the top of the pitch. Instead of traversing right to the anchors make a wild hand traverse to the LEFT along a big flake. The flake is solid. This will take you into Zip Code just above its crux move. Now finish on the great upper part of Zip Code. There is a fixed anchor at the top of the pitch. Rappel down the upper pitch of Pony Express to the bolted anchor above Mescaline. One more rap from here to the ground. Single 60m rope required.
Never done that but sounds like a really interesting climb, because Zipcode is so good but otherwise inaccessible to the 5.9 climber. Thanks for pointing out that potential.
