Y: Middle Cathedral - East Buttress 10/8/05 - SAC We did this as 2 teams of 2, with Anne-Sousig Steunou and I in the first team, and Christopher Bourez and Niloy Mitra in the second. Anne and I climbed rapidly, but Chris was having problems because he didn't have enough cams. While I was waiting for them to catch up, I took about 30 minutes to extract a stuck cam from the 3rd pitch; we left at the chain belay for them to use. I took a little time on the crux pitch (50 Crowded variation, 5.10a), being careful to find the easiest way to do the traverse and then getting good pro on the thin crack section. Anne cruised when following, and then we waited a bit and gave Chris a toprope. By this time we were in the shade for the rest of the day; the temp was warm enough for climbing, but a bit cool for waiting. I led 4 more nice pitches (p6-9) to the tree belay at the base of the final 5.8 pitch, while Chris led up a roof variation instead of the easy but sparsely protected face which joins the standard route at the fixed pin. Anne couldn't clean a cam in the corner below the tree belay, so I rapped down on the single rope and got it. I went a bit further down and got a biner from a single titanium piton rap anchor; then I talked with Chris. I left the rope dangling so he could get a toprope once he got a bit higher. I climbed back up p8-9 with my ATC on the fixed rope as a backup belay. After a bit more waiting, we belayed Chris up. I led the 5.8 pitch, Anne followed, and Chris led part of it and got a toprope for the rest. On the final pitch, Anne and Chris climbed followed on my rope in the fading light, and Niloy followed in full darkness (very dim moonlight). After changing shoes, we went up the 3rd class, roping up for awhile in an exposed section. We lost the trail up to the Catwalk briefly and then slowly moved along it. The main problem at this point was that we had just one headlamp (somewhat dim) between the four of us. I had left mine at the base, since I had promised Jared we'd be down before dark. We eventually reached the gully, did the raps, and downclimbed the talus gully. Niloy was fairly tired and he needed extra time to get good footing. By the time we reached the car it was 3am. This would have been somewhat OK if we had our own car, but Jared, Darko, Sam and James were waiting for us since before dark. They were dozing a bit in the cars while waiting and a ranger thought they were merely sleeping in the cars and had a conversation with them. Fortunately they came back and were there when we returned. We got back to Palo Alto at 7:30am....
