4 People, MR, Sep 30 - Oct 2

My first time doing it this time of year.. according to NOAA historical data for Crabtree Meadow -- which is at 10,700' (the closest thing I could find to historical temps for UBSL), air temps look to be in the 15-30F range during this timeframe. I'm a long time skier (Colorado, Switzerland, Austria), and have done MR in June (when iceberg, chute, and last 400' were snow covered) but I'd love to hear thoughts on gear and clothing choices from those that have done MR during this time of year.
