Aardvark just posted a message about MR conditions on Mar 5. We were ascending that day and saw several people who had camped at Iceberg Lake but just came straight down due to whiteout conditions. Our group went from the road closure at 6:30am to Iceberg at around 4, with overnight packs, so even with skis you should be able to get quite far in a day. We used snowshoes the whole way above the portal (until right below Iceberg, where there's a short steeper section). A total of 10 folks were camped there Sat night, and we all headed up the MR the next morning (beautiful sunny day). Nine of us turned around at the notch (at various times) due to high winds in the chute. One brave guy made it up and down (the hard part!) the chute. The snow was generally soft rather than crusty along the whole trail, and should be good for skiing -- though I'm pretty ignorant along those lines. Good luck, stay safe, and have fun!
