Approach: Use the access trail just before the East Trapps Connector Trail meets the carriage road; about a 4-minute walk from the Uberfall. At the cliff, walk right and locate Arch, a prominent rock arch above the East Trapps Connector Trail. Ribs starts at the arete on the right side of the arch.
P1: Start on the large arete and quickly traverse over into the middle of the face on the right. Climb nearly a straight line up to the GT ledge, with one or two overhang moves just before the finish. 5.5, 130'.
Although this can be done in two pitches, I recommend combining pitches to avoid belaying at the bolted rappel station 80' up.
Descent: Two rappels with a 50m rope from bolted rap anchors.
Protection
Cams of all sizes in horizontals. Pass one bong and rap chains midway up.
This climb goes straight up a rappel highway. Wear a helmet. The ledges above have loose rock and even a soft rope can hurt when it's tossed from 100'. Just ask my wife...
