On October 11, you can earn a new souvenir for celebrating the geocaching game board. What’s that, you ask? The whole entire Earth! (and one lonely space station). All you have to do is go out and find an EarthCache on International EarthCache Day.
EarthCaches don’t have physical containers, but instead bring you to a unique location and teach you an earth science lesson. To make the find, you’ll have to check the EarthCache’s description and answer questions based on where you are. You can send your answers to the cache owner via Email or the geocaching.com Message Center.
Visit the search page to find an EarthCache near you, just set the filter to EarthCache and there you have them all.
