The Historic Buffalo Geotrail consists of 10 geocaches located in Stamping Ground and the surrounding area. Each registered individual will receive a passport at the event detailing the coordinates and significant history of each of the 10 sites. At each site you will need to locate the geocache container that contains a custom stamp to show that you have visited there. Stamp the corresponding block for each geocache location. Upon completion of all 10 geocaches located along the Historic Buffalo Geotrail, bring your completed passport back to the event area and you will receive a stuffed buffalo, event magnet and other items while supplies last.
