geocache

Geocache is a hidden container placed at a precise location as part of the activity known as geocaching. Participants use GPS-enabled devices to navigate to the coordinates, then find the cache, sign a logbook, and often log the find online. Many caches also contain small trinkets or trackables that move from cache to cache and are tracked as they travel.

Geocaching began in 2000 after GPS accuracy improved for civilian use. A programmer and hobbyist, Dave Ulmer, hid the first cache, “The Original Stash,” in Oregon to test the concept, and the practice quickly grew into a global hobby with Geocaching.com and other platforms serving as central hubs for listings, logs, and trackable tracking. Today, millions of caches have been placed worldwide, offering a broad range of locations and challenges.

How it works: Cachers hide caches with a description, clues, and a hint about size or difficulty. Each cache is assigned coordinates and a listing that explains how to find it and how to log the experience. Found caches are logged online, and cachers may exchange items inside the container, though many caches are simply logbooks. Trackables, such as travel bugs and geocoins, travel between caches with owners tracking their journeys.

Cache types include traditional caches (a single location), multi-caches (stages with another set of coordinates), and mystery or puzzle caches (solving a puzzle yields coordinates). Event caches are gatherings for geocachers. EarthCaches provide education about geology or environmental science and emphasize responsible field observation.

Etiquette and safety: Seek permission where required, respect private property and the environment, and follow local laws. Practice Cache In Trash Out to minimize impact, carry appropriate gear, and be mindful of weather, wildlife, and safety concerns.
