Geocache / Letterbox
Geocaching is an outdoor game using hand-held GPS devices or by placing GPS coordinates into Google maps on smart phones. It is effectively an inexpensive, interactive, tech-related treasure hunt that’s a great way for all ages to learn geography, spend time outdoors together, and explore new sites and areas. Participants use location coordinates to locate hidden geocache containers called caches. Once you find a cache, take a trinket and leave one of your own behind, sign the logbook, and share your experiences through Geocaching.com.
Geocache “treasure hunting” game is played in all 50 states and throughout the world by adventure seekers. Some caches are easier to find than others. The biggest reward is the thrill of the search and the discovery of a place where you perhaps have never been. Geocaching also has minimal impact to the environment.
The District hosts an ongoing geocache series on conservation sites (go to geocaching.com, create an account and drop in zip code or area you want to treasure hunt), and hosts a GeoCache Challenge each year with a different themed geocoin as the end prize.
