Geocaching is an activity where an individual or team uses a global positioning system (GPS) to locate different treasures, otherwise known as caches. Caches are usually placed in wooded area of parks, or areas that are off the beaten path. Seekers then use the latitude and longitude of the item locate the cache. In most cases caches are some type of container that you leave an item in, and then take and item out of. Caches also frequently have logs to sign and/or cameras to document those who found it.
