YouTube caption: "In spite of warnings by descending climbers that the route was not passable above Trail Crest our team reached the top of the highest mountain (14,505feet) in the contiguous United States and the first and only team which reached the summit after the last storms till that weekend."
It appears to be a SF Bay Area meetup group. About 15 people started out, maybe a third made the summit. A couple of shots after dark on the summit, though they didn't take gear to camp on the summit. Must have been a very long day. They base-camped at Outpost camp.
