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.
