I was there just after it opened this year. There was only me and a family of four in a car with CA plates. A woman in their party asked if I had ever been there and I said yes, about 45 years ago on a fire. Her husband then said he was on a fire here in 1973 and he began counting off the decades with his fingers and we realized that we had been there on the same fire. He couldn't find any landmarks that were familiar to him and the only thing that was familiar to me was the airstrip which we slept next to in paper sleeping bags. (are they still issuing those?) I remember being flown in a helicopter across a canyon to work on a steep forested hillside. On this visit I couldn't identify that hillside or the bare ridge down towards the river that we also worked on. I drug my teardrop trailer up here and spent the night nearby.

The point of this long story is that this is the strangest coincidence I have ever encountered. They came from California and I came from NW Washington on the same day and each stayed a few minutes but yet we met!

As for the monument: I don't think you could occupy this station with a survey instrument because it's so close to the walkway.

Found this while visiting the lookout tower here at Hat Point. Benchmark is slightly under the walkway. RM2 is in a rock next to the trail to the walkway entrance.

I happened upon the reference mark number 2 benchmark while visiting the Hat Point lookout.

Found the hat point bench mark and the reference mark number 2. Reference mark number 1 must be under the walk way or not there anymore. Same for Hat Point old mark.

Control Text

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  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)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