Allegany State Park Geobash (ASPGB or ASP Geobash) is a geocaching “Mega Event” held every May at Allegany State Park. A Mega Event is a regularly held (usually annually, as is the case with ASP Geobash) social gathering of geocachers.  To quality as a Mega Event, an event must have at least 500 participants each time that it is held.

Geocaching is an outdoor recreational activity, in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called “geocaches” or “caches”, anywhere in the world.

A typical cache is a small waterproof container containing a logbook (with a pen or pencil). The geocacher enters the date they found it and signs it with their established code name. After signing the log, the cache must be placed back exactly where the person found it. Larger containers such as plastic storage containers (Tupperware or similar) or ammunition boxes can also contain items for trading, such as toys or trinkets, usually of more sentimental worth than financial. Geocaching shares many aspects with benchmarking, trigpointing, orienteering, treasure-hunting, letterboxing, and waymarking.

Geobash will be held May 20-22. For more info, visit
