I believe that this one was lost to construction. A few years ago they had the whole lawn torn up to work on underground lecture rooms. I suspect that the monument was removed in the digging.

The benchmark should be in the torn up area just to the right of center.

Well the grass had grown (to a degree) and we certianly werent about to tear up the library lawn and dig 6+ inches down. With the re-grading of the lawn it may even be deep now. we found the references though. I bet this one is still under there.

across Prospect street are the 2 refernce disks as well as another BM. For the 2 further ones. i had a boy stand right by the mark.

Probably not a good idea to go searching for this one as it appears to be a newly planted lawn.

IT IS 18 FEET N OF THE CENTER OF A CINDER ROAD LEADING PAST THE TENNIS COURTS AND PROJECTS 4 INCHES. AT THE TIME THE WORK WAS DONE THE UNIVERSITY AUTHORITIES DESIRED TO LOCATE THE POSITION OF THE NEW ASTRONOMIC BUILDING, SO AN ADDITIONAL REFERENCE MARK WAS SET. IT WAS CEMENTED IN THE MACADAM ON PROSPECT PLACE, NEAR ITS INTERSECTION WITH MURRAY STREET AND FITZRANDOLPH STREET. THE MARK IS SET FLUSH, 10 FEET N OF THE S CURB OF PROSPECT PLACE. 15 FEET S OF THE N CURB. AND 15 FEET E OF THE EXTENSION OF THE CENTER LINE OF FITZRANDOLPH STREET. AS THE MARK IS PRESUMABLY NOT PERMANENT AND IS NOT VISIBLE FROM THE GROUND AT THE STATION, NO NUMBER WAS GIVEN TO IT. IT WAS STAMPED PRINCETON 1933. THE ANGLE AT THE STATION, FROM THE REFERENCE MARK TO A MARKED STONE IN THE FACE OF THE NEW ASTRONOMIC BUILDING WAS MEASURED BY THE OBSERVING PARTY, AND THE OTHER ANGLES WERE MEASURED BY THE UNIVERSITY. TO REACH THE STATION FROM THE MAIN SECTION OF TOWN, GO E ON THE MAIN STREET TO WASHINGTON ROAD, THEN S (RIGHT) ON THIS STREET TWO BLOCKS TO PROSPECT PLACE. TURN E (LEFT) AND GO ABOUT 1/2 BLOCK TO THE FIRST WHITE BUILDING ON THE N SIDE OF THE STREET. THIS IS THE ASTRONOMIC BUILDING AND THE SITE OF THE STATION.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in May 1999.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in April 1995.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • 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.
