On May 3 2000, Dave Ulmer, a computer consultant, wanted to test the accuracy by hiding a navigational target in the woods. He called the idea the “Great American GPS Stash Hunt” and posted it in an internet GPS users’ group. The idea was simple: Hide a container out in the woods and note the coordinates with a GPS unit.
The finder would then have to locate the container with only the use of his or her GPS receiver. The rules for the finder were simple:
“Take some stuff, leave some stuff.”
Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices.
Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location.
*A great summer activity.* Some helpful websites:
Geocaches can be found all over the world. It is common for geocachers to hide caches in locations that are important to them, reflecting a special interest or skill of the cache owner. These locations can be quite diverse. They may be at your local park, at the end of a long hike, underwater or on the side of a city street.
Maybe Geocaching is a little like Pokémon Go, but it has been going for a long time… even before GPS, when compasses were used for scavenger hunts. It is a fun way to explore and learn more about the local area that you live in!
