Best poker hand this weekend is Four of a Kind. Here is another B.
It seems that the County Park Service has bought the land from Agilent Technologies. I wonder what they plan to do with the Telephone Pole Forest? Much less the ocean and the ship! (My father worked here for a while before he went on the trip to lay the Transatlantic Cable from Newfoundland to Scotland. Or was it before he went along when they laid the cable to Hawaii?) Station recovered easily. Reference Mark 2 also recovered. I didn't imagine 'ten paces' being up that steep a hill!

RECOVERY NOTE BY NEW JERSEY GEODETIC SURVEY 1939 STATION AND REFERENCE MARKS FOUND AS DESCRIBED. A NEW AZIMUTH MARK, A STANDARD DISK SET IN CONCRETE, AS DESCRIBED IN NOTE 11A, AND STAMPED BELL RESET 1939 WAS ESTABLISHED AT THIS STATION.

01/01/1945 by CGS (GOOD)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1945 (RCE) ORIGINAL DESCRIPTION OF THE NEW AZIMUTH MARK IS FITTING, EXCEPT THAT PHRASE - AND 46.82 FEET NORTHWESTERLY FROM A NAIL IN POLE NO.1783 - SHOULD BE DELETED, SINCE POLE NO.1783 HAS BEEN REMOVED. AT THE TIME OF THE RECOVERY, IT WAS NECESSARY TO EXCAVATE SEVERAL INCHES OF SOD IN ORDER TO EXPOSE THE MARK TO VIEW. THE IMPORTANCE AND VALUE OF THE MARK WAS EXPLAINED TO THE LANDOWNER, AND HE WAS REQUESTED TO LEAVE IT UNCOVERED SO THAT THE NEXT MAN WHO NEEDS TO USE IT WILL NOT HAVE TO DIG FOR IT. IT IS BELIEVED THAT THE LANDOWNER WILL COOPERATE IN THE MATTER.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in May 1999.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • 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.
