AT LYNDHURST. AT LYNDHURST, BERGEN COUNTY, 0.2 MILE WEST ALONG THE DELAWARE, LACKAWANNA AND WESTERN RAILROAD FROM THE STATION, AT THE EAST END OF THE BRIDGE OVER PASSAIC RIVER, IN THE TOP OF THE NORTH CAP-STONE OF THE EAST ABUTMENT, AND ABOUT 8.5 FEET NORTH OF THE CENTERLINE OF TRACK 1. A 1-3/4-INCH ROUND CASTING, LETTERED U.S.E.D. H.L. STA. NOTE-- THE DELAWARE, LACKAWANNA AND WESTERN RAILROAD IS NOW THE ERIE LACKAWANNA RAILROAD.

- 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 June 1991.
- 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.
