Not only was bailing annoying, but it turned out to be a lot more unnerving than expected. One hazard we hadn't considered was that as the day warmed,the rocks lining the ridge above would drop ever-increasing amounts of rocks down our slope. Since the entire ridge is line with rocks, there reallyis no line that is safe from this, and the lower we got, the more exposed we were to rockfall from above.
I have become accustomed to the buzzing sound that rocks make when they fly by in the air, but in this case the slope was low angle enough andsoft enough that rocks did not sail, but it was steep enough that they still flew down at very high velocities, but the soft snow dampened the soundof the incoming missiles. Smaller rocks made a rat-tat-tat-tat noise like a machine gun, growing louder as the pinwheel got closer. There were evensome large, flat, table-sized blocks that just made quiet hissing as they shot down the slope. They carried enough momentum that if they hit oneof us or snagged the rope, things would have gotten bad in a hurry.
Needless to say, we moved as fast as we could until we neared the massive bergschrund, then took our best guess on where we might find acrossing. Just as we began traversing to what looked like a pinch in the 'schrund, direct sunlight started to appear on the rocks and slopes above,and rocks began raining down at a much higher rate. We booked it to a short, steep cliff band that would provide protection as rocks sailed overheador were deflected to the side.
From there we could see maybe one spot with a bridge large enough to climb over, but it was thin and looked likely that we would punch through.Plus it was in the line of fire. The snow where we hid was supersaturated and as I climbed along the rock edge I kept sinking in up to my waist orsometimes deeper if I hit the moat. This was not solid enough to make a safe bollard out of. After some searching along the rocks I managed to find aplace to build a reasonably sufficient anchor out of a nut and cam. We built up the anchor and I rappelled off the lip and into the bergschrund, whichwas much too wide to clear.
