My old high school friend in Ft. Worth Texas was walking around his neighborhood and spied the following*:
All I could tell him was that it is 0.21 feet above the Elevation of the Beast. Further investigation shows it is southeast of Bluebonnet Circle:
32 41' 52.26179"n, 97 21' 33.28393"w
… and it appears you can see it on the curb in this street view. It’s mid-lot so it is doubtful that it marks or references a property corner. Or a curve point. Don’t let the homeowner's claims in the background confuse you. This is not at the North Pole.
*I’m happy to report that since my visit to Ft. Worth earlier this spring he says he notices all kinds of survey monuments now. I’m glad I could warp yet another citizen’s mind.
Possibly tied to some network of City benchmarks being assembled by someone under contract to the City. Might be a sort of TBM to help tie together the primary network with spots that aren't GPS-friendly.
gotta love the coordinate to 0.001'!!
It's got a DIMPLE...so it must be GOOD!

Yes, that is a puzzler, isn't it, but it turns out that is an Oklahoma DOT control point. Long story, but the short version is that when the survey party was sent to stake out the point (in Oklahoma, the engineers decide where they need a control monument and give the survey parties the coordinates where it should be installed, repeating the process if the control monument turns out to be missing the original target, which is why they are typically bolted instead of grouted), the latitude stamped on the plate given them was wrong by more than a degree and they ended up in Ft. Worth.
And here I was thinking it was a memorial set by the Polar Expedition Team of the University of Texas to commemorate their triumphant discovery of the North Pole.
Ft. Worth, Texas...
I don't know what it is either, other than a fairly accurate way-point on somebody's Garmin.
But given the Ft. Worth crime rate, I do know that now its location has hit the internet the chances of it surviving until the morning light are slim! (insert rim-shot)
I was trying to think of some witty retort to Kent's crack about ODOT....sadly it's probably true...But being an Okie my Union Card says I have to reply to all derogatory remarks concerning Okies (especially from folks from Texas).
Now before you click on the link I feel compelled to explain that I have nothing against Ft. Worth. I did know an extremely talented young lady from Ft. Worth years ago. AND I can't think of anything else you could have stuck between Dallas and Weatherford but Ft. Worth. 😉

Well, I wasn't sure about the Oklahoma DOT origin of the mark.
I mean, "feet" and "inches" aren't spelled out as you'd expect. The stamping, though, is obviously a shop stamping. "Hey, go set these control points at the coordinates stamped on them."
Ft. Worth, Texas...
If it was shop stamped you've got to wonder if they accounted for the thickness of the plate when they stamped the elevation.:-D
This looks like something I would do in my yard. Perhaps a surveyor lives there?
If he's a surveyor, he must be putting all his profits back into his equipment as opposed to plowing it into his residence...:-P
It looks like your typical GIS control point.
Ft. Worth, Texas...
though, is obviously a shop stamping
That's the puzzle isn't it? How the he## do you get that thing stamped that well after you locate the dimple, or how the he## to you stake the thing at that prestamped coordinate? I've gotten pretty good at stamping in ground monuments, but not that good:-O

Actually, if a person really wanted to use that form of control point, I'd think that the way to do it would be to drill the holes in the concrete for the two fasteners using a template for a guide, and then get a position and elevation for the point midway between them using a jig made with a blank plate and a couple of studs that fit the holes with minimal clearance.
As long as the jig and plate have their reference points midway between the centers of the holes, the shop-stamped plate as installed ought to mark the original surveyed point pretty well.
For that stupendous precision in coordinates, isn't the punch mark rather large? I mean where inside of that punch mark dimple is the actual location? I am inclined to agree it was located by some really fantastic GIS software package that derives its accuracy by the number of decimal points it will print out in the little window that pops up with a left mouse button click.

It looks like Rudolph didn't make it out of Texas, as evident in the attached picture. Someone will be dining on reindeer for dinner this Christmas.
same pile of leaves from nov/dec to june?
this could be a subversive plot... perpetrated to stymie the efforts of gps localizations everywhere.

I was told as a child that an Okie was just a Texan on his way to Colorado. Thats how my fathers family got here anyway.
