Geocaching (pronounced geo-cashing) is an activity for the entire family, individual, or any group. The goal, using a Global Positioning System (GPS) receiver, is to find a hidden cache.
A cache may be as small as a pencil erasure to as large as a car – but usually about 4 X 4 inches, which contains a log, on which to write your name, and often some trade items, or swag, if you remove an item you are supposed to leave something else, of like kind, in its place.
Caches are placed for many different reasons; present a challenge to find, share a special location with others, or education about some facet of a given location. Education is the main goal of the National Museum of Natural History’s GeoTour. The cache pages and the puzzles involved are to introduce you to some of the active research by the museum’s scientist. To take you beyond the exhibits and introduce you to the wide variety of materials on the museums many web sites.
