What is Geocaching?

Geocaching is an outdoor treasure-hunting game where participants use a Global Positioning System (GPS) device or an app on a smart phone to find containers (called “geocaches” or “caches”).

A typical cache is a small waterproof container containing a logbook and “treasure,” usually toys or trinkets of little monetary value. When you find a cache, write the date and your name in the logbook, then trade a trinket you brought for one in the cache.

Today, well over 480,000 geocaches are registered on various websites devoted to the sport. According to Wikipedia, geocaches are currently placed in over 100 countries around the world and on all seven continents. Geocaching, says Wikipedia, “is similar to the 150-year-old letterboxing, which uses references to landmarks and clues embedded in stories.”

EarthCaches and Virtual Caches Inside Yellowstone Park

Burying containers or disturbing natural environments are prohibited inside a national park, so to claim that you "found" the cache, you must answer a question to prove you were there.

Geocaching Outside of the Park

With over 80% of its 5,000 square miles made up of public lands, Sublette County, Wyoming and the Pinedale area are ideal for the new high tech sport of geocaching. Grab your GPS, map and compass and head out to discover country rarely traveled since the early fur traders. Be sure to follow all the rules of the “Tread Lightly” code, and obey local signs and regulations.

Geocaching - Waypoints of the Heart

Now I've discovered the perfect pastime for people like me. For Christmas, I bought my husband the Garmin eTrex GPS unit he'd been drooling over. He wanted it for marking waypoints while he was hunting or taking photographs. I wanted it because I'd learned about geocaching.
