Reconsider
You may want to reconsider your plans. My group of four hikers did Marshall, Redfield and Cliff this past weekend (3/4-3/5). We broke trail on all three peaks and the toughest thing we did all weekend was come down from Cliff through the "winter" route. I believe we came down in the right place, having never done it before, but the descent was horrible. Pin Pin commented last week that you probably don’t want to do it due to spruce traps; well he wasn’t kidding. There is so much blow down covered with four feet of snow that it was totally exhausting just going down hill. Granted, it’s broke out now, but I’m sure it would still suck. Do yourself a favor and hike around to the normal trail. We broke that out and it wasn’t too bad.
