Geocaching is an outdoor recreational activity in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called "geocaches" or "caches", at specific locations marked by coordinates all over the world.

History

Geocaching began shortly after the removal of Selective Availability from GPS on May 2, 2000, which significantly improved the accuracy of GPS devices. The first documented placement of a GPS-located cache took place on May 3, 2000, by Dave Ulmer of Beavercreek, Oregon. He called the activity the "Great American GPS Stash Hunt" and posted the coordinates of the first cache online. The idea quickly caught on, and the term "geocaching" was coined by Matt Stum on the "GPS Stash Hunt" mailing list on May 30, 2000.

Equipment

The primary tool for geocaching is a GPS receiver or a GPS-enabled mobile device. Other useful items include a map, a compass, and a pen or pencil to sign the logbook found in the cache. Some geocachers also use geocaching software to manage their finds and searches.

Types of Geocaches

There are several types of geocaches, including:

• Traditional Cache: The original type of cache, consisting of a container and a logbook.
• Multi-Cache: Involves two or more locations, with the final location being a physical container.
• Mystery or Puzzle Cache: Requires the geocacher to solve a puzzle to determine the coordinates of the final cache.
• Event Cache: A gathering of geocachers, organized by a geocacher and posted on a geocaching website.
• EarthCache: A type of virtual cache that involves learning about a geological feature.

Geocaching Websites

The most popular website for geocaching is Geocaching.com, which is operated by Groundspeak Inc.. Other websites include Opencaching and TerraCaching.

Geocaching Etiquette

Geocachers are expected to follow certain guidelines to ensure the activity remains enjoyable and sustainable:

• Respect the environment and local laws.
• Do not place caches on private property without permission.
• Trade items of equal or greater value when taking something from a cache.
• Sign the logbook and log the find online.

Geocaching Community

The geocaching community is active and diverse, with participants of all ages and backgrounds. Many geocachers participate in geocaching events, where they can meet other enthusiasts, share experiences, and learn new techniques.
