International EarthCache Day is Saturday, October 12th through Sunday October 13th. In 2018, the STEM Center developed a program to celebrate and spread awareness of International EarthCache Day. You can still participate in this program. And, if you complete 5 of the 6 EarthCaches, you will receive a geocoin. Visiting these EarthCaches is a great way to learn more about the environment around you. Read more about our program here.
