I'll drop what I've found here in case anyone else comes by.
The "corridor" is cut in 'twain by a bit of a jumble of crevasses, and most people now traverse to the right into a fairly open snowfield, then zig-zag up until they get up below the bergschrund. At that point it's a high traverse to the right and up the ramp to the snow cap. You *can continue straight up to the upper part of the corridor, but you need good snow conditions as pick placement and crampon points need good purchase to mantle yourself up and over. Some people have been jumping that crevasse on the way down, but it started turning people around as the weekend progressed. A number of snowbridges are going to collapse soon, including the one just up the hill from Schurman.
Weather was beautiful for our acclimatization and relaxation day on Saturday and lots of teams found the summit. On Sunday morning, we were the first team out of camp at 12:30, and just after the sun came up around 13K' some clouds and fog came in, so we didn't get any views or much time on the summit. It cleared up later on our descent. Lovely time.
