When the GPS signal degradation called Select Availability (SA)
was removed by the Clinton Administration May 1st, 2000 (statement),
it opened up the possibility of games like this one.
On May 3rd, a container of goodies was hidden by a someone
outside of Portland, Oregon - in celebration of the removing of
Selective Availability. By May 6th the cache was visited twice,
and logged in the logbook once.
Mike Teague was the first to find the container, and built his
personal web page to document these containers and their locations
that were posted to the sci.geo.satellite-nav newsgroup.
In July of 2000, Jeremy Irish found Mike Teague's web site and
found his first cache outside of Seattle, Washington. Recognizing
the potential of the game (but never expected the growth), Jeremy
approached Mike Teague with a new site design, used the name
Geocaching, and developed a new web site adding virtual logs,
maps, and a way to make it easier to maintain caches as the sport
grew. The site was alive for a while, but the official torch was
passed to Jeremy on September 6.
Since the launch of the web site, the Geocaching sport has
grown to caches in all 50 states and over 100 countries. There are
now many variations of the game, including virtual caches, offset
caches, puzzle caches, and multi-stage caches. New ideas and new
great games crop up every day.
From its inception, Geocaching.com has been developed and
maintained by Jeremy, with the assistance of Geocachers around the
world. Many thanks to the Geocaching community for making the game
it is today. The official web site for Geocaching is
Who knows where it'll go next!
