Kindly come join us.

We have an informative presentation by Baltimore County's Pat Simon, who recently recovered long-lost Crown Stone 40 on the Mason-Dixon Line . . . broken off and buried since 1902



This illustrated presentation by Pat Simon gives an interesting step-by-step explanation of the entire 5-year Mason-Dixon Survey, which was one of the greatest scientific achievements of its age, performed immediately following the French & Indian War. His talk includes many little-known facts about the survey gleaned from Charles Mason's actual journals and notes. It also tells, for the first time, the saga of Crown Stone 40 on the north line of Harford County (and south line of York County)

Original Mason-Dixon Crown Stone 40 was apparently deliberately broken off in 1902 by a resident farmer, who left its base buried in his field. A replacement Stone 40 was then set along the state line nearby, not on any correct even mile but clear of the farmer's property. That stone also disappeared. For decades thereafter, nothing marked the line, but in 2014 Pat Simon and his staff from Baltimore County Survey Department successfully recovered the ancient buried remnant of original Stone 40, still in the farm field where Mason & Dixon themselves placed it in 1766.

Plans are underway to carve an exact full-size replica out of Indiana limestone, exactly matching the original English-made stone. With luck and a little fund-raising, Maryland Society of Surveyors will install a NEW Crown Stone 40 this year.


Professional Land Surveyor Pat Simon, Chief of Surveys for Baltimore County MD, was first introduced to surveying while still in high school, at Baltimore Polytechnic in 1975. He's been enjoying it ever since. He spent 28 years in the private sector, starting as an entry-level rodman and working his way up to licensure in 1987. He joined the county government in 2003. Pat has taught on a wide range of surveying subjects from basic to very advanced, and had a featured article published in POB Magazine. During his career he's seen the profession evolve from logarithms to handheld micro-computers and beyond. All Carroll Chapter attendees will remember the superb presentation Pat Simon gave us a few years back, on the Resurvey of the Baltimore County-Carroll County Line --- an enormous historic-retracement effort he directed. That was one of the finest, most memorable talks our chapter ever experienced. Pat currently serves as vice-president of Maryland Society of Surveyors.


Certificates for One (1) PDH will be awarded by the chapter to all licensed attendees.


Bogey Macaws Restaurant is located at 601 Chestnut Hill Road, York, PA.
