Here is what Geocaching.com has to say -
Celebrate International EarthCache Day – Geocaching.com
Explore the Secrets of the Earth
Join the International EarthCache Day celebration on October 14. Each EarthCacheteaches visitors about the playground all geocachers enjoy – the earth. An EarthCache takes adventurers to a unique site showcasing geological features. Simply discover and log an EarthCache, or attend an EarthCaching event, this Sunday to take part in the worldwide movement.
EarthCaches can reveal why a giant boulder came to rest in the middle of a prairie or how a river flows in two opposite directions in one day. Instead of finding a container at an EarthCache, geocachers learn and report their geology discovery to log a smiley.
There are now more than 14,000 active EarthCaches around the globe. Go to the official Geocaching.com Facebook page to share your International EarthCache Day experience.
And I found this little vid to help explain it, just in case you are like me and have never participated in this day.
I will head out and see what I can find. I will also be searching for a few folks who have done their EarthCache for the day. I am hoping that Joshua Johnson will have a fun video of his day.
Check back later to see what I can find.
