Hi there, I went up the MR this Saturday during the little fit of snowfall. Conditions were not ideal, but not bad enough to turn around. About 11 of us summited in about 8 hours from the portal.
As for the final 400', it was pretty reasonable to get a good grip with the axe and crampons, but some of the snow was not consolidated yet and as we climbed, the "dippin' dots" filled the boot tracks fairly quick.
If anyone is planning on going, be careful on the traverse back, the snow was very fresh and our axes went straight down to geanite with very little crust. I would assume by today, it should be packed in a lot more. Going down the 400' was not an option due to the amount of snow that was falling once we reached the summit. Happy trails, here's a video showing what it's like to climb the final portion, it was my first time on this route. I plan on coming back and trying the east buttress in the future. https://youtu.be/LRm3gDd0C0U
