Dear Students, 

   On September 15, 2018 our class will be taking a field trip to Purgatory 
   Chasm. This is a Massachusetts state park located in Sutton, MA that offers 
   challenging and scenic hiking trails, including one that we will be taking 
   over large boulders scattered in a deep gorge.  For more information, please 
   see: 

     http://www.mass.gov/locations/purgatory-chasm-state-reservation

   There are specific steps that you should each take to make this a safe and
   positive experience:

   * The hike will include slippery boulders that have been worn smooth by
     hikers.  In addition, there are occasional gaps in the rocks you will
     need to traverse.  For these reasons, please war supportive footware
     with soles providing good traction (hiking shoes or sneakers), not sandals, 
     dress shoes with smooth soles, etc.

   * Purgatory Chasm can present a real risk of injury.  Stay away from the
     edges of the chasm and do not try to climb the chasm walls or tall 
     boulders.

   * During the hike, please wear sunscreen.

   * There may be mosquitos, ticks and other insects.  Wear bug spray.

   * You will want to bring a backpack, water bottle, phone, etc.

   * If you have any questions or concerns, please consult with me before
     our trip.

   Schedule:

   * Load bus(es) at Hogan 3 (parking lot entrance) starting about 8:50am

   * Depart at 9:00am sharp

   * Return to campus by 12:00 noon

   * Note: Because of the nature of the terrain in the park, we will not
     attempt the trip on September 15 if it is raining.  Substitute 
     rain date is SUNDAY, September 16 on the same schedule.  Watch for
     communications from Prof. Reents (Natural World Director) if it looks
     like we will need the rain date.  

   Note: Because we will be getting back to campus in time for you to get
   lunch, we will NOT be providing the box lunches I mentioned before.  There
   will be snacks provided, but not drinks (see point above about water bottles).
