Information from Brian Cooley, our advisor from the Maryland Geocaching Society:

The Maryland Geocaching Society (MGS) was founded in 2002, and was among the very first to organize around the adventure and passion of geocaching. Over the years, the Society has welcomed over 3500 members to their website and has supported a wide array of state-wide geocaching activities. These activities include geocaching events and public outreach programs; working closely with Federal, State and local agencies, to promote geocaching as an earth-friendly pursuit; provide educational outreach to youth groups; promote “Cache in Trash Out” programs to assist in the maintenance of parks and trail systems. The MGS promotes geocaching as an exciting, earth-friendly and adventurous outdoor recreation activity for the whole family.

The MGS has been a leader in working with government agencies to develop, plan, and organize regional Geotrail and Geotour’s. A “geotrail” is a series of caches tied together by a common topic or theme. Here in Maryland, we are proud to claim that we were the first state in the U.S. to ever develop a state-wide Geotrail! Visit to learn about geocaching in Maryland!

About Geocaching:

Geocaching, pronounced “geo-cashing,” is a worldwide phenomenon, in which participants use a hand-held GPS (Global Positioning System) to plot map coordinates in order to locate a hidden treasure or “cache.” Searching for a cache is akin to going on a treasure hunt and can involve clues, riddles and visits to multiple locations. Shovels are a forbidden tool – caches are never buried.

Global Positioning (GPS) receivers tap into a satellite network from anywhere in the world to accurately pinpoint specific geographic locations. A geocacher can place a cache anywhere in the world, pinpoint its location using GPS technology and then alert others to the cache’s existence and location via the Internet. Anyone with a GPS receiver or smart phone device can then hunt for the cache.
