Found with the fam on a beautiful day over the Memorial weekend.

Located during our hike to the top of Escudilla

Hiked up to the top with our hiking group. We hoped to climb up the tower but it was very windy.
The trees were beautiful

Recovered station ESCUDILLA along with RM 2 in good condition. The surface of RM 1 has been damaged and its stamping no longer legible.

It's still there and in good shape. Found the beat-up one also - just a few feet away.

The golden benchmark!
As mentioned, RM1 is in bad shape, but still there.

HMMM!? Is that real gold?

Found Reference Mark 1 and the survey mark itself.

With the storms coming in we did not search for RM 2.

Marker is in good shape while RM 1 is illegable.

photoRM 1 baddly scared

Located it easily and in good shape near the lookout tower at the top of Escudilla Peak.

Found this benchmark in great shape. Also found one of the reference marks but it was too badly scared to determine which one. Never mind, this is not a reference mark, it is the benchmark.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 1993.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)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.
