An alright climb, this offwidth can be fun... if you're into offwidths. The bottom 15 feet (crux) especially offer the opportunity to practice your chicken-winging, handstacks, and knee locks. Reach the big ledge midway up, take a deep breath, and then climb the inside face behind the massive flake. Unless you brought BIG gear, don't expect pro from here until you reach the top.
If you're a completist, give this one a shot, otherwise there are better climbs for your attention.
Roughly 10 meters left of the swallow nests in the corner of the Swallow Wall, at the right (east) end of the Slab Wall, behind the Inclined Boulder, is a broken offwidth crack under the left edge of a huge flake. It only gets bigger as it goes up... Walk off.
Trad gear. The crack is wide, so bring the big stuff, like a #5 if you've got it. There are a couple of slots that will take smaller cams as well. No bolted anchor: you'll have to build one at the top. Bring some more big stuff (#3 maybe?) for that, or just walk off.
