The North Olympic Library System is introducing three geocaching kits that are now available for checkout. Using the global positioning system (GPS) and your wits, geocaching brings together a love of the outdoors and modern tools of navigation.

Geocaches may be found everywhere and the basics of the game are simple: Participants select a cache from a website; after a cache is selected, the coordinates to the location are entered or downloaded onto a GPS device. It is then up to the players to use their navigational and detective skills to seek out the hidden vessels. Caches may contain a simple logbook for those who’ve found it, or perhaps a small treasure to share. Participants traditionally leave an item in exchange.

Each kit contains a Garmin eTrex10 GPS device, “The Complete Idiot’s Guide to Geocaching” and a simple quick start guide. Patrons may borrow each kit for up to three weeks. To reserve a kit, call or visit any NOLS library, or visit the online catalog at www.nols.org.
