Who are we?
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.
Established in 1888, GSA provides access to elements that are essential to the professional growth of
earth scientists at all levels of expertise and from all sectors: academic, government, business,
and industry. GSA's membership unites thousands of earth scientists from every corner of the globe
in a common purpose to study the mysteries of our planet and share scientific findings.
