Found this one from the car as we went by trying to get to some parking! It's been spray painted around in neon orange and hard to miss!

Benchmark found at Montvale Rest Stop off the Garden State Parkway.

It's too easy when they mark them with spray paint!

Found the benchmark with no problem. I was at the rest stop checking out my nearby cache for maintenance.

  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
