Gear Requirements for All Winter Trips to the Summit

  • Due to space limitations on the snowcat, all belongings must be condensed as much as possible. For day trips, we recommend bringing a single day pack per person. For overnight guests, one duffle bag (no wider than two car seats) and one day pack per person works well.
  • All essential outdoor gear items must be readily accessible while in transit to/from the summit station
  • Any trip participant who is not appropriately prepared with the required gear is subject to dismissal from the trip
