Found it! Gate was locked so we hiked the last mile up to the lookout. Tripod Fire is still making for a smoky view!

Found current lookout tower as described. It is centered over the benchmark TQ0444.

I'm not sure if this benchmark is referring to the old LO or the current one.

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  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)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.
