Found this one this morning. I have seen this pad of concrete thousands of times turning out of my neighborhood. It is in the right-of way on personal property. This is north of the mountain bay trail bridge on Cardinal Lane on the west side of the street.

This has to be one of the best finds today! We got to the location and thought we knew where it had to be. We searched high and low all over the old railroad bridge without success. After getting our bearings, we realized, the coords were pointing us 200 feet north. Looking that way, we found the witness post in the front yard of a private residence. Went over to check the data and sure enough, it was the BM we were looking for!

I would love to ahve one of these in my yard! BM was in good condition about ~5 feet off the sidewalk on the front lawn of a private residence.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in November 1991.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • 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.
