Spotted this benchmark while grabbing the nearby geocache.

Found as described. Previous logger aptly described RM1.

Found the mark in good condition, also found RM1 in damaged condition, RM2 was not recovered it should have been located in the road and parking area. The mark is on the north side of a rough access road to the Lewis & Clark Monument which is approximately 250' west. RM1 is on the south side of the road and has been bent up from people trying to get it out of its' rock setting.

We were along with grandpa GEO*TRAILBLAZER 1 and TIGGR our grandma when we recovered the mark.

We were lucky enough to be with our Grandpa,GEO*TRAILBLAZER 1 and our Grandma TIGGR when they recovered this mark.

THIS ONE IS THE SECOND FAVORITE BENCHMARK.

THE VIEWS ARE AWESOME.
YOU CAN NEVER SHOW OR DESCRIBE THE FEELINGS YOU GET WHEN YOU COME TO A PLACE LIKE THIS.
I WISH I COULD VISIT A LOT MORE OFTEN.
BUT THIS WILL PROBABLY BE MY ONCE IN A LIFETIME.
I AM APPROXIMATELY 1 MONTH AHEAD OF THE EXPEDITION 200 YEARS LATER.

RIGHT ON TRACK FOR ME.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in July 1992.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
