We were planning a trip to the Emmons this weekend and bailed due to fresh snow cover on the crevasses. I did the DC a month ago and can tell you if not for the guides' trail the South East side of the mountain would be a route finding nightmare due to all the melted snow bridges.
If you do go, be sure an post the report!
