ON A HIGH HILL OPPOSITE THE MOUTH OF ELK RIVER. THERE WAS A BATTERY HERE DURING THE CIVIL WAR AND THE HILL IS SOMETIMES CALLED BATTERY HILL. THE OLD RAMPARTS ARE ON THE HIGHEST PART OF THE HILL AND THE STATION IS AT THE NORTHEAST CORNER JUST OUTSIDE THE DITCH AND JUST INSIDE OF THE FENCE SEPARATING A CLEARED FIELD FROM THE OLD FORT WHICH IS OVERGROWN WITH TREES AND BUSHES. THE STATION IS MARKED BY A NAIL IN THE TOP OF A STAKE AND 2 FEET UNDERGROUND BY AN EARTHENWARE PYRAMID. A BLACK WALNUT TREE IN THE CLEARED FIELD IS ABOUT 50 METERS N. 69 DEG 47 MIN E. (MAG.) FROM THE STATION AND A HOLE DRILLED IN A ROCK IS 3.05 METERS S. 48 DEG 07 MIN E. (MAG.) FOUR OAK TREES, EACH MARKED WITH A BLAZE AND A NAIL, ARE AT THE FOLLOWING DISTANCES AND MAGNETIC DIRECTIONS FROM THE STATION- 4.48 METERS S. 24 DEG 15 MIN E., 11.1 METERS S. 5 DEG 42 MIN W., 11.9 METERS N 71 DEG 20 MIN W., AND 14.25 METERS N. 50 DEG 32 MIN W.

- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998.
- 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.
