This benchmark was recovered in good condition. The North Baldy Lookout Tower was dismantled in 1989, but the concrete supports still remain and may aid in locating the disk. The views from this location are outstanding!

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1991.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
