EarthCache™ Collection

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. A portion of the sales of official EarthCache™ items will go to support the work of the GSA.

For 2022, International EarthCache Day is October 9th.  Earn the 2022 souvenir when you find an EarthCache on October 8th or 9th!
