Sure enough, reference mark 1 leads you straight to the actual benchmark disk! No evidence of the witness post mentioned in the 1966 description.

Since Reference Mark 1 is in the pathway folks are finding it easily and then logging a find for it on the Mitchell 2 benchmark page. Geocachers not completely familiar with benchmarking tend to log any marker they find to the nearest benchmark listing. We need to compare the disk markings with the benchmark description.

Reference Mark 1 is NOT the benchmark. To log a Reference Mark as found it needs to have its own page which this one does not. But the cool thing about a Reference Mark is that it has an arrow that points to the primary benchmark. Simply follow the arrow and you will find Mitchell 2. It's about 50' or so from the Reference Mark.

This page is for the Station Mark. The Reference Mark should be logged as a Note on this page.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in March 1994. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.
  • 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.
