This is actually the first crux of The Caterer, which can be used to approach Spiders From Mars. This crux is rated 11d I think in Rolofson's new guide.
Alex is actually climbing Spider from Mars, a 5.11b trad line just to the right of Jungle Blues from Jupiter. This is the 1st crux where Alex is about to get his right foot even with the small horizontal crack. That'll enable him to reach good holds above the bulge.
