Cindy got to us just before dark. Apparently some of the clustering on the slab pitch slowed them up a lot, as well as just slowing down as the day wore on. Chris and Dominique still hadn't summitted by sunset. We eventually managed to get into contact with them, about a pitch below, and after giving some assistance (I lowered Cindy down on rope), we were all on the summit at midnight.
We picked our way down the exposed 4th class ridge. The weather had cleared up, but it was pitch black, making the routefinding difficult. I was going into auto-pilot mode as I hadn't gotten much sleep that week and was now pushing nearly 39 hours with virtually no sleep since Friday morning (I think my brain decided to clock out at about midnight as I had been expecting to be asleep by then!).
We reached a spot where the ridge seemed to cliff out, just about 100' short of the saddle, and as I was investigating a reasonable way around the impasse, the others decided we were close enough to the gully that maybe we could rappel into it. Normally I would have been very resistant to this idea as I don't like to rappel unless it is absolutely necessary (It usually is not the quick and guaranteed escape that many people tend to think it is). But I was so tired, I just followed along. So Scott offers to take the blame for this one while I was mentally AWOL :-P (Actually, Scott only offers 95% responsibility. Some of the others offered various percentages as well for themselves, and naturally my passiveness with the rappel factored in to things. How shall we proportion responsibility among 6 people? . . . eh, let's just say it was one big cluster that led to the bivy).
One rappel led to another, which led to another, which led to another, which led to another, and then the rope didn't reach any more anchors. Hmmm . . .
We were at a small, sloping ledge beside a tree, the weather was nice, and we only had a few more hours until sunrise by now anyways, so we decided to bivy and work out how to get down in the morning when we could see better.
I was nice and comfy sleeping inside my backpack while hanging on a gear anchor and managed to get a good amount of snoozing (I was last down on the rappel and there was not enough space for me by the tree). The others huddled in a pile under a single space blanket beside a tree. Unfortunately they couldn't fall asleep while I was able to. Fortunately, I was far enough away that they couldn't take out any frustrations on me and my snoring :-)
