EarthCaches are filled with pools of geological knowledge, just like Pamukkale in Turkey. These bright blue, eye-catching terrace pools are created by the carbonate mineral left by the thermal flow of spring water, pictured above.
Learn more about Earth and its incredibly unique formations on Saturday, October 7, and Sunday, October 8, in celebration of International EarthCache Day! Earn the official souvenir for visiting the physical location of the EarthCache and completing the logging requirements to receive your smiley.
All non-Premium EarthCaches are open to everyone throughout the weekend on the Geocaching® app from 11:00:00 UTC on Friday, October 6, until 10:00:00 UTC on Monday, October 9.
EarthCaches do not have physical containers. Instead, they take you to a unique geological feature and teach you something about the area, just like Pamukkale. What kind of EarthCache will you visit on International EarthCache Day? Find an EarthCache near you!
