a revisit after 10 years and much improved knowledge on locating these stations :)
It also helps that many other have provide excellent info and pictures of the station as well..
I will add mine now as well

Found while biking the D&R canal.

Found it.®

N 40° 24.507 W 074° 59.110

Fairly easy find by description. The station is on the northeast side of the lock. It is northwest from the dirt road over the southeast part of the lock. Ordinal directions are a bit off. We looked around the lock, and espied the station near the railing of the walkway over the lock.
Hand-held GPS coordinates: N 24º 34' 30.4" W 74º 59' 06.6" Not too bad for scaled coordinates.

The needle pointed onto private property. The description I found very confusing. There ia also a reconstructiuon project going on here. Needless to say this was no find.

Control Text

  • 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.
