Geocaching is a fun “treasure hunt” activity where explorers use GPS devices or cell phones with tracking devices to search for “treasure caches” that have been hidden in various locations by other geocachers. The caches typically consist of small containers with trinkets, and the larger ones can be ammo boxes as shown on the left. Geocachers are allowed to take a trinket in exchange for leaving another. The coordinates are then logged online or automatically with new GPS devices.
Finding a cache is simple:
1) Log in to Geocaching.com (it’s free!) to get coordinates which can be downloaded to a handheld GPS unit.
2) Follow the signal to the cache.
3) Take or leave a treasure.
4) Log your find on the Geocaching.com website.
