is an outdoor recreational activity, in which the participants use a
Global Positioning System (GPS) receiver or mobile device and other
navigational techniques to hide and seek containers, called "geocaches"
or "caches", anywhere in the world.
A typical cache is a small
waterproof container containing a logbook where the geocacher enters
the date they found it and signs it with their established code name.
After signing the log, the cache must be placed back exactly where the
person found it. Larger containers such as plastic storage containers
(Tupperware or similar) or ammunition boxes can also contain items for
trading, usually toys or trinkets of little financial value, although
sometimes they are sentimental.
