OPERATIONAL NOTES

Geocaching &endash; There is a new web-based activity called geocaching that has affected several National Park Service areas. The Ranger Activities Division asked Olympic NP SA Mike Butler to investigate. Here’s his report: Geocaching is an activity in which participants hide a cache and take a position at the location using a GPS receiver. The position is then published on the group’s web site with an invitation to search for the “treasure.” Caches often contain a notebook or log book and something the finder may take. The finder is asked to put another item in the cache for others to discover and will often report the find on the web site. Several caches have been found in National Park Service areas. The webmaster for the site (www.geocaching.com) has been contacted. He was very surprised that geocaching is illegal in NPS areas, and understood NPS concerns about the damage geocaching has and can cause to historic, archeological and natural sites. He agreed to work with the Service to discourage further geocaching activities in parks.

Two related activities were also discovered. Letterboxing (www.letterboxing.org) is a phenomenon similar to geocaching in that a player takes directions from a web site and uses those directions to find a hidden object. In letterboxing, the directions come in the form of a riddle and the hidden object is a stamp which the finder can use to stamp a piece of paper to prove that he has visited the site. The web site showed the location of at least two letterboxes in parks. The parks have been notified, but the Service has not yet contacted the webmaster or game managers. The Degree Confluence Project (www.confluence.org) is another web-based activity where people try to visit various latitude and longitude integer degree intersections and report their findings on the web site. In this case, however, no objects are placed in the ground, and there are no apparent regulatory violations in areas where cross-country travel is allowed or where the confluence is not on a protected site. There has been no attempt to contact the project organizers. [Mike Butler, SA, OLYM]
