We transitioned from the glacier to the ridge at about 4PM and climbed an easy diagonal system of cracks to the ridge crest. Not long after reaching the ridge crest, we each found niches for a bivouac and settled in for the night at about 8,500 feet. We were seeing some lightning to the northwest and were concerned that we would be in a vulnerable place if the storm headed our way, but we were committed at this point. We hoped that the red sky at night adage held.
