Geocaching is a type of global treasure hunt of people looking for caches, or hidden stashes of objects. Geocaching may also be described as a series of hide-and-seek games, where hiders provide online clues for seekers. Seekers use global positioning system (GPS) devices to find hidden caches.
Caches are the hidden treasure. After registering online, geocachers look for coordinates (the longitude and latitude) of caches. Caches have two or three parts: a waterproof container, a logbook to list the people who visit the cache, and sometimes a low-cost trinket or geocoin. (Geocoins are metal medallions made by individual geocachers or organizations. Like other cache items, geocoins are not worth much money.) Common materials found inside caches might include foreign currency, keychains, ornaments, or booklets. Valuable objects, food, or other items that could be easily damaged are not allowed in geocaching.
Although caches can be hidden (as false rocks or behind real ones), they are not buried. Latitude and longitude provide the caches location. Geocachers also give clues online. For example, a cache may be hidden on one side of a tree, or may only be visible from a certain angle. Because geocachers want the hobby to remain safe for people of all ages, caches are located 150 feet from railroad tracks.
Some caches are drive-up (also called cache and dash), but most require a good walk. For this reason, geocachers are advised to bring a map, a GPS device, an extra set of clean clothes, and an umbrella. Continue reading from National Geographic
