GENERAL LOCATION, BURLINGTON, VT., AT THE UNIVERSITY OF VERMONTS CENTENNIAL FIELD. TO REACH FROM THE U.S. ROUTE 2 BRIDGE OVER I-89 AT EXIT 14 IN SOUTH BURLINGTON GO WEST ALONG U.S. ROUTE 2 FOR 0.35 MI (0.56 KM) TO THE INTERSECTION OF EAST AVENUE ON THE RIGHT. TURN RIGHT AND GO NORTH ALONG EAST AVENUE FOR 0.55 MI (0.89 KM) TO THE INTERSECTION OF UNIVERSITY ROAD RIGHT. TURN RIGHT AND GO EAST ALONG UNIVERSITY ROAD FOR 0.1 MI (0.2 KM) TO A GATE TO CENTENNIAL FIELD. PASS THROUGH THE GATE AND CONTINUE STRAIGHT AHEAD ON A GRAVEL DRIVE BETWEEN GRAVEL AND PAVED PARKING LOTS FOR 0.05 MI (0.08 KM) TO THE MARK ON THE RIGHT BETWEEN THE GRAVEL DRIVE AND THE NORTH EDGE OF THE PAVED PARKING LOT. THE MARK IS SET IN THE TOP OF A 60 CM DIAMETER CONCRETE BASE FOR THE MOST EASTERLY OF A ROW OF LIGHT POLES. THE BASE PROJECTS ABOUT 0.45 M (1.48 FT) ABOVE THE PAVED PARKING LOT. IT IS 6.4 M (21.0 FT) SOUTH OF AND ABOUT 0.9 M (3.0 FT) HIGHER THAN THE CENTERLINE OF THE GRAVEL DRIVE, 10.8 M (35.4 FT) WEST OF THE NORTHWEST CORNER OF THE WOODEN TICKET OFFICE BUILDING, 17.5 M (57.4 FT) NORTHWEST OF THE SOUTHWEST CORNER OF THE TICKET OFFICE, AND 43.3 M (142.1 FT) SOUTH OF MARK FOUL BALL.

- The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
- The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in January 1997.
- The geoid height was determined by GEOID99.
- The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
- The modeled gravity was interpolated from observed gravity values.
