International EarthCache Day

Many of readers of this blog are outdoor enthusiasts. One “game” that has gained in popularity among outdoor enthusiasts is Geocaching. Geocaching is basically a high-tech treasure hunt where people get coordinates for a hidden geocache from a website called They then enter those coordinates into a GPS receiver, or into their GPS-enabled smart phone (with an App) before going to search for the geocache out in the woods.’s Geocaching 101 page has a lot of great information about the hobby, as does this video:

This coming Sunday, October 14 is International EarthCache Day. EarthCaches are a special type of geocaches where instead of a traditional cache there is some sort of earth science education lesson for the geocache hunter. It’s been a while since I’ve been out geocaching (being a graduate student takes a lot of time). However, I have a blast every time I go geocaching. As wetland and soil scientist, earth caches are always extra fun because I get to learn (or be reminded) about some awesome scientific fact! Many of these EarthCaches highlight a unique geological feature of a particular location.

There is a Facebook page for International EarthCache Day. There’s also more information about EarthCaches on, and on

If you go geocaching on Sunday looking for an EarthCache, and you find one that teaches you about soil, or any other interesting earth science fact, please come back to this blog post and tell everyone about it in the comments section!

Happy caching!
