|DESCRIBED BY COAST AND GEODETIC SURVEY 1934
ABOUT 1-1/4 MILES WEST OF JEFFERSONVILLE, ON THE MACON, DUBLIN AND SAVANNAH RAILWAY, 8 TELEGRAPH POLES WEST OF ROAD CROSSING, 21.00 METERS (68.9 FEET) SOUTH OF SOUTH RAIL, ON EASTWARD TANGENT OF NORTH RAIL. REFERENCE MARK = X-26 46.0 FEET NORTH OF CENTER LINE OF U.S. HIGHWAY 80, 21.6 FEET SOUTH OF SOUTH RAIL, 25.918 METERS (85.03 FEET) FROM STATION IN GRID AZIMUTH 127 DEG 24 MIN.

|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1949 (CMT)
THE DESCRIPTION PLACES THE STATION INSIDE THE CONCRETE PAVED SURFACE AREA OF U.S. HIGHWAY 80 WHICH WAS PAVED SINCE THE STATION WAS ESTABLISHED. APPARENTLY THE LOCATION WAS EXCAVATED TWO FEET OR MORE WHEN THE HIGHWAY WAS PAVED, THEREFORE THE STATION IS BELIEVED DESTROYED.
A REFERENCE MARK WHICH IS ONLY NUMBERED AS B.M. X 26 IS ABOUT 1.4 MILES VIA U.S. HIGHWAY 80 W OF THE RAILROAD STATION AT JEFFERSONVILLE, ON THE MACON, DUBLIN AND SAVANNAH RAILROAD RIGHT-OF-WAY, MIDWAY BETWEEN TWO RAILROAD GRADE EXCAVATIONS, OPPOSITE THE CENTER OF A ONE-ACRE FIELD, 56 FEET N OF THE CENTER LINE OF U.S. HIGHWAY 80, 21.6 FEET S OF THE RAILROAD S RAIL, AND 3 FEET ESE OF THE RANGE DETERMINED BY TELEPHONE POLE 687 AND A HIGHWAY APRON DRAIN. THE MARK IS A BRONZE REFERENCE DISK SET IN CONCRETE, IT PROJECTS 2 INCHES, AND THE DISK IS STAMPED TIME X 26 1918 ELEV. 539.960.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1997.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
