Found all the benchmarks. The azimuth is 200 ft south of the trail when it reaches the ridge line at the saddle. The coordinates are N32.85837 W116.72796 .

I found the two reference disks, but not the actual marker.
I did see an area on a nearby boulder that loooked as though it had been patched.
I had not preread the info on this one.

Found the benchmark disk near the Viejas Mountain summit cairn and the stone wall enclosure. Also found three reference marks, if I recall correctly.

Happy Mothers Day. Coordinates N 32 51.674 W 116 43.559

found this am while out geocaching on viejas mtn..tfth!

Found one of the disks. Looks like the one this one points to is MIA; there is a hole in the rock.

I found this on a nice solo hike up the hill. I also found a couple of nearby caches then stayed and enjoyed the view for awhile before heading back.

it's still there!

Fd this guy while geocaching on a lovely day for a hike

Found this one on a nice hike up the mountain. It was on the outer edge of some piled on rocks, but I found it!
Good Times! SlabyMom

I stopped by this one during a great day of a caching with the SDCET: Miragee, Radio Racers, Team Geogeeks and Toby's Gang. It was very cloudy but pleasantly cool today!

Found this benchmark along with Toby's Gang, Miragee, Trailgators and Radio Racer.

Found this benchmark along with a couple of caches nearby.

Found with my boys. The youngest two of the 3 cd's found them.

nice walk, very clear. Great day! hike only took about 1:30 with a slop at the top.

Incredibly clear, crisp day. Wonderful area for a hike. Benchmark is right where it's supposed to be.

Living in the area made this benchmarker the ideal one to locate for my myself, a friend, and our two Boy Scout sons. The trailhead is easy to locate. Since the recent rains however the trail has many loose rocks and footing can be very unstable.

I found this benchmark after being the FTF on the nearby "Tax Freedom Cache," GCNHYE.

Drat. I forgot my camera, but this guy is still intact in in place in a boulder at the north end of the windbreak.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in June 1996. 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 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.
