Located in Dingman Township, Pike County, Pennsylvania. The land is part of the Delaware Water Gap National Recreation Area. The private road listed in the 1959 recovery is closed and posted as 'off limits'. I parked on Conashaugh Road, off Zimmerman Road where the horse riding trail enters the woods heading northeast. The trail meets the closed private road near one of the wellhouses. Continue up the steep ridge to the station. Station disk and RM 1 located as described. RM 2 was not recovered. Since it was listed as missing, and with the hundred foot drop off, I did not look for RM 2. I attempted to observe the azimuth station "High Point Monument", but I could not see it from here. Total climb: about 450 feet in about a half mile. Beautiful day and nice views. It always worries me when the vultures are swooping below me!

  • The orthometric height was scaled from a topographic map.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
