The Truckers’ Geocaching Resource


Geocaching was developed by Dave Ulmer near Portland, Oregon in 2000. It is an adventure activity where people use GPS receivers to find hidden treasures called caches. In geocaching, a participant places a cache in a container and then hides it at a certain location. The person who hides the container then posts the geographical coordinates of that location along with other information about the location on an online geocaching listing service. People who wish to hunt for the cache use the information from the listing service site along with a hand-held GPS device to try and locate the cache. It is generally understood and expected that when a cache is found the contents are removed by the treasure hunter and replaced with new contents for the next hunter. 

Getting started in geocaching is fairly simple. What is needed to search for geocaches is a hand-held GPS receiver, online access in order to search for cache locations on geocaching listing services, and topographic maps to aid in the search. People who want to place caches need the above equipment along with a heavy-duty water-proof container and a treasure to place inside it. Log books are also typically placed within a cache. This is so that the cache hunters can record their find. Occasionally, participants who place a cache will put a disposable camera in the container in hopes that the person who finds it will take a picture of themselves with the treasure. Later on when the camera is full, the cache hider can develop the photos and place them on the listing site or on a personal web site.

Geocaching is a great activity that can be enjoyed alone, in a group, or with one’s family. It is especially popular with people who love the outdoors. This activity and several variations have spread worldwide from its origins in Oregon.
