About us


Who are we?
The EarthCache program is part of The Geological Society of America's (GSA) Education and Outreach effort in partnership with Geocaching.com and other partners around the world.

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 growing 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.

The Education & Outreach Department of GSA is a small dedicated group whose goal is to raise the awareness of the importance of Earth science to all.

The key people in the EarthCache program are Gary Lewis and Matt Dawson (caching names: - geoaware and geoawareHQ) and they have a wonderful dedicated team of "Geoaware" volunteers around the globe who work with cache developers to continue to grow the list of published EarthCache sites.

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 US 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 was placed by geoaware on 10 January 2004 on a headland in New South Wales, Australia.  "EarthCache I" (GCHFT2).  A few more were places in Australia and Colorado, USA during 2004.   Within the first year over 500 EarthCaches were published and the number has grown dramatically.  

Since the program started, over 3.5 million people have logged that they have visited EarthCache sites and the number is growing exponentially.

GSA is very proud to be part of the exciting geocaching community and hope we can continue to add value and wonderful Earth science experiences through the EarthCache program.
