found while walking around campus.

Found the tiger guarding the survey disk, then I found the survey disk. The front of Nassau Hall had numerous visitors posing for photos. Three young women even asked me to take a picture of them. Nobody but me, however, seemed to be looking for the benchmark!

I think the benchmark coordinates may be off by 100 feet or more. I neglected to record a waypoint when I got to this survey disk. Perhaps the next finder can record the coords and post online?

I was out at lunch today looking for a few before the rain hit. This one is pretty easy (if you remember to look down ).

Note how close to the wall of Nassau hall this is, right behind the East Princeton Tiger

Real Ivy League Ivy here! This shows the East Tiger, steps and entranceway to nassau hall. The arrow points the the flat disk in capstone.

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 1992. No vertical observational check was made to the station. * This is a POSTED BENCH MARK height. Code NC indicates the bench mark was located on a no-check spur therefore a value was not computed.
  • 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.
