While vacationing on M.D.I. I decided to search for a few local benchmarks. I drove out along Route 233 from Bar Harbor to the intersection of Route 198 and with some difficulty found the mark using the distances & bearings in the historical description. At the station my Garmin GPSmap76 receiver indicated approximately 394 feet from the posted coordinates. The disc was buried under three inches of dirt and moss and not at all visible, but it is in very good condition. ~Rich in NEPA~
