Each year, The Geological Society of America celebrates International EarthCache Day on the first Sunday of Earth Science Week and the last Sunday of World Space Week.
International EarthCache day items include a patch, trackable tag and Geocoin (each sold separately)! A portion of the sale of every EarthCache Day item will go to support the work of the GSA.

2018 EarthCache™ Geocoin and tag set include the full size geocoin and a separate trackable tag. Both are trackable at Geocaching.com with a unique icon. They are each tracked separately with their own individual code. That way you can keep this amazing coin in your collection to be discovered while sending the tag out to find geocaching adventures throughout the world.
