A little history ...

In 2003 at a GSA conference, a GSA members suggested that the Society become involved in geocaching.

A meeting was then held with Geocaching.com along with some land manager partners, such as the U.S. National Park Service, to consider a program that would meet land manager issues as well as develop a way to teach the geocaching community something about Earth science. Based on those discussions, a set of basic guidelines were developed which form the core of the current EarthCache publishing guidelines.

The first EarthCache ("EarthCache I" [GCHFT2]) was placed by user "geoaware" on 10 Jan. 2004 on a headland in New South Wales, Australia. Since then, over 28,500 EarthCache sites have been published in over 200 countries/territories, and they have been visited more than 6 million times.
