Since the first EarthCache (GCHFT2) was placed on 10 January 2004 an amazing5.6 million people have visited over 19,200 EarthCaches in 165 countries around the globe. That is a truly outstanding impact - people outside, having fun and learning about our dynamic planet all at the same time.

Throughout the eleven years the program has established some programs and events that aim to support EarthCachers and have helped to build a community of EarthCachers.

However, these programs require your support. The EarthCache program is administered by The Geological Society of America and we rely on the financial support of our EarthCache community to keep the wheels turning.

What would your support allow us to do:

Build the EarthCache Academy - an online learning adventure where EarthCachers can learn more about Earth Science. Estimated cost $8500 a year.

Increase support for events based on Earthcaching (stickers, pins, coins and other materials to hand out at events). Estimated cost $3000 a year.

Bring “A” class speakers to the International EarthCache Event Estimated cost $2500 a year.

Participate at teacher/museum conferences to train educators on using EarthCaches in the classroom. Estimated cost $3500 a year.

Supporting the EarthCache Program is as easy as 1,2,3

All donations to the EarthCache Program will go through The Geological Society of America Foundation.
