1901? stone monument, OPUS shared solution


Recommended Posts

I found this magnetic station in 2011 and got a short article in the county newspaper.  I wanted a commemoration that surveyors might notice also, so I took several hours of GPS data and submitted an OPUS Shared Solution.

These stations were used to measure magnetic declination and to let local surveyors calibrate their compasses by sights to landmarks.
