 BW0108
 BW0108.The horizontal coordinates were scaled from a topographic map and have
 BW0108.an estimated accuracy of +/- 6 seconds.
 BW0108
 BW0108.The orthometric height was determined by differential leveling
 BW0108.and adjusted by the National Geodetic Survey in June 1991.
 BW0108
 BW0108.The geoid height was determined by GEOID99.
 BW0108
 BW0108.The dynamic height is computed by dividing the NAVD 88
 BW0108.geopotential number by the normal gravity value computed on the
 BW0108.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 BW0108.degrees latitude (g = 980.6199 gals.).
 BW0108
 BW0108.The modeled gravity was interpolated from observed gravity values.

 BW0108
 BW0108'DESCRIBED BY COAST AND GEODETIC SURVEY 1969
 BW0108'2.6 MI N FROM BROOKHAVEN.
 BW0108'ABOUT 1.7 MILES NORTH ALONG THE ILLINOIS CENTRAL RAILROAD FROM THE
 BW0108'STATION AT BROOKHAVEN, THENCE 0.9 MILE NORTH ALONG A BLACK TOPPED AND
 BW0108'GRAVELED ROAD, NEAR THE NORTHWEST CORNER OF A TRIANGULAR SHAPED STEEL
 BW0108'FENCE AROUND AN ILLINOIS CENTRAL RAILROAD MICRO-WAVE TOWER WHICH IS
 BW0108'270 FEET HIGH, IN SECTION 31, R 8 E, T 8 N, 231 FEET WEST OF THE
 BW0108'CENTER LINE OF THE GRAVELED ROAD, 5.5 FEET NORTHWEST OF THE NORTHWEST
 BW0108'CORNER OF THE CONCRETE BASE SUPPORTING THE TOWER, AND IS A DISK BRAZED
 BW0108'ON THE TOP OF A 3 INCH PIPE WHICH PROJECTS 1 INCH ABOVE THE LEVEL OF
 BW0108'THE GROUND.  NOTE-- THE TOP OF THE DISK IS AT ABOUT THE SAME ELEVATION
 BW0108'AS THE TOP OF THE BASE OF THE TOWER.  THE GATE TO THE TOWER IS LOCKED
 BW0108'AND THE KEY IS IN NEW ORLEANS, LOUISIANA.  MARK WAS SET OUTSIDE DUE TO
 BW0108'THE ABOVE REASON.
