MY0714.The horizontal coordinates were scaled from a topographic map and have
MY0714.an estimated accuracy of +/- 6 seconds.
MY0714
MY0714.The orthometric height was determined by differential leveling
MY0714.and adjusted by the National Geodetic Survey in June 1991.
MY0714
MY0714.The geoid height was determined by GEOID99.
MY0714
MY0714.The dynamic height is computed by dividing the NAVD 88
MY0714.geopotential number by the normal gravity value computed on the
MY0714.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
MY0714.degrees latitude (g = 980.6199 gals.).
MY0714
MY0714.The modeled gravity was interpolated from observed gravity values.

MY0714''DESCRIBED BY NATIONAL GEODETIC SURVEY 1934
MY0714''2 MI W FROM OAKDALE.
MY0714''2.0 MILES WEST OF OAKDALE, WORCESTER COUNTY, NEAR SHAFT NO. 2
MY0714''OF THE METROPOLITAN DISTRICT WATER SUPPLY TUNNEL, ON THE
MY0714''RIGHT-OF-WAY OF THE BOSTON AND MAINE RAILROAD, 19-1/2 FEET NORTH
MY0714''OF THE NORTH RAIL AND 15 FEET SOUTH OF POLE 88 OF THE POWER
MY0714''TRANSMISSION LINE FOLLOWING THE TUNNEL. A STANDARD BENCH MARK OF
MY0714''THE METROPOLITAN DISTRICT WATER SUPPLY COMMISSION. THE POINT
MY0714''ON WHICH THE ROD IS HELD IS THE UPPER END OF A 3/4 INCH IRON
MY0714''ROD, THE BOTTOM OF WHICH IS IMBEDDED IN A CONCRETE BLOCK ABOUT 1.5
MY0714''FEET SQUARE AND SET 6 FEET BELOW THE GROUND. THE ROD COMES TO THE
MY0714''SURFACE INSIDE A 3-INCH IRON PIPE WHICH IS SPREAD AT THE BOTTOM
MY0714''AND CAPPED AT THE TOP. ROD AND IRON CASING EXTEND 1 FOOT ABOVE
MY0714''THE GROUND.
