Found while looking for a nearby virtual geocache.

Walk past this little guy a few times a week. As well as the unlisted across the way.

Found while looking for a nearby cache. Surprise that this one wasn't in the database too.

photoOh state database, where art thou'?

Walking back from Straub look at what I found. Its cool how these just show up randomly. I'll need to walk to the other side to spot the unlisted one too one day.

Found it. Am reporting to NGS.

Made it to the other side of Thomas Square today and found the other un-listed State Survey disks. 2-13B 1971 Too bad GeoCaching.com missed so many of the disks.

Found this on a run to City Mill. I'll hunt for the other on the other side of the park another day.

This is the unlisted benchmark mentioned by cache_man2004 and DadWrap. It's a State of Hawaii marker stamped 2-13B 1971 and is located at N21 18.215 W157 50.925.

Found this one today. Fairly easy, it's only a block from my apartment...

Relatively easy to find once you find parking. Also found the unlisted one on the other side of the park.

These things are everywhere, not noticed them like I do now. I have been to this park many times. This time I found a free parking place.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1998. 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 determined by vertical angle observations. No vertical observational check was made to the station.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
