January 10th, 2014 marks 10 years since the placement of the very first EarthCache; Earthcache I - a simple geology tour of Wasp Head GCHFT2 near Durras, Australia by Geoaware.
10 years later, there are over 17,000 EarthCaches placed around the world, including 37 in New Hampshire, helping geocachers better understand the planet and the processes that form and shape it.
While you are here celebrating, if you have not completed Concord Granite, GC2T3ET now is a good time. 2 smilies at 1 stop.
