The Bassett magnetic station is an example of one of the early USC&GS bronze disks placed in concrete. These bronze disks were flat on top instead of domed as they became in later years. The description for the Bassett magnetic station first appeared in the USC&GS Special Publication No. 36 which detailed the magnetic observations made during 1915. It is assumed that the station was placed during that year. Prior to 1915 most of the magnetic station bronze disks were placed in limestone posts instead of concrete. It is located in the northeast corner of the courthouse grounds and is just below the surface of the grass.
