A FIELD TRIP TO THE NORTH SHORE

  FINAL CALL FOR THE NORTH SHORE FIELD TRIP

May 19-May 21


Due to health issues, four people have reluctantly
decided to give up their coveted seats on the bus
for the field trip to the North Shore, A waiting list
has been used up, so I can offer this trip to a few
lucky people.

The trip would start at about 4 PM on Friday, May 19
and end Sunday evening, May 21, and a bus will
provide most of the transportation.

If you would like to go, please e-mail or call me,
as soon as possible.

I tried to remove people from this mailing list
who are already on the trip. If you think you are
on the trip and yet received this, please e-mail
or call me.

4PM Friday, May 19 – Sunday evening, May 21, 2006

Trip Leader is Professor Richard Ojakangas

We will leave the Twin Cities by bus at 4PM, Friday, May 19, travel to Duluth and stay over Friday night at the Canal Park Inn.  We then leave at 8AM and travel along the North Shore, staying at the Grand Portage Casino Hotel Saturday night.  We return to the Twin cities Sunday evening. May 21. 

We should see many signature “textbook” rock formations, vesicular and amygdaloidal rocks, waterfalls galore, and have a few opportunities for collecting.  An extra perk:  stories of Ojakangas’  life living in Northern Minnesota—from his childhood to the present, growing up on a farm on the Iron Range, his worldly travels….  His personal stories about the area on the last trip brought out the richness and character of the area, like frosting on a cake.  Also, trip participants might bring their books to be autographed by Professor Ojakangas.

The total cost will be approximately $115 to $120 per person assuming double occupancy, not including food or tips.  Of this, $50 pays for the leader and bus combined, assuming a full bus of 54 people, and $65 to $70 per person pays for the two hotel nights combined, assuming double occupancy.  Not included are food, and tips for the bus driver as we;; as people who serve food (if not a buffet), possibly tips left in rooms; for those few who bring or take home the kitchen sink, tips to luggage handlers and rock movers are not included.  A group meal will likely be arranged for Saturday evening.  People could join the trip in Duluth and we might accommodate people wishing to stay in State Parks.

If interested, please contact Bill Robbins as soon as possible.
