You don't need to go on an archeological dig to find the Earth's hidden treasures. Through the process of EarthCaching, treasure hunters of all ages can discover ancient mountains, sunken forests, and countless other gems. Unlike Geocaches, which entail the hiding and seeking of man-made objects, EarthCaches already exist in the natural world. Be it a fossil bed, a crater, a peninsula, or another geological wonder, EarthCaches reveal how a place was formed and the scientific value of that place. With little more than Internet access, a GPS receiver, and a sense of adventure, EarthCachers get a behind-the-earth view of Mother Nature's marvels. In addition to learning about existing caches, youth/adult partners can teach others about caches in their own community.
