Are you planning your summer vacation?  Are you looking for
something new and adventurous?

    Earthwatch is a non-political, non-profit organization which 
organizes volunteers to work with scientists on expeditions in 60
countries around the world, including many expeditions in the United
States.  You can go for a week or a month, or however much time you
have.  For example, you could help research volcanoes in Costa Rica or
help rescue Cape Cod's marine life.  You could work with
archaeologists unearthing tombs in Egypt or with an Australian ecologist
who needs help collecting data on Kangaroo Island's plants.  If you have
mountain climbing skills, you could help a Wyoming mammologist take a
Big Horn census in the Rockies.  You could observe porpoises from a 
dinghy off the coast of Hawaii.  This is just a small sample.  There are
many, many more.

Your transportation to and from expeditions, all membership costs,
and all expedition costs are 100% tax deductible.  For information

MA 02272.
