Today was lovely, if a bit humid after the strong Central Texas rains yesterday that washed the dust off of everything and left the air at the ranch heavy with the scent of cedar. It was late in the day when I got back to the 1879 land grant corner, so I settled for cleaning up the mound with whisk broom and gloved hands, sweeping away ninety years of cedar duff, and setting a rod and cap marker in the center of the mound after making a careful study of the pattern of the stones.
Yes, the rod and cap is 4.6 varas distant from the fence that the 1927 surveyor described as being 4.6 varas distant from the mound as he found it then, most likely intact and without a cedar growing out of it.
The way back to the truck was a hike that passed this vista along a ridge covered with Texas madrones.
Sooooo... did ya RTK that puppy, or leave an L1/L2 receiver to cook on it all night (or maybe a flyby with your L1 chicken bucket)?

That will get tied in with my 4600LS L1-only units. They give very good accuracy in the baseline solutions on baselines under 10km. The target for everything positioned by the survey is +/-5mm WRT NAD83 (as realized by the local segment of the CORS network) in N and E components. If I wanted to relax it to +/-3cm, I'm sure RTK would be the hot ticket.
Kent I'm curious why you didn't cut down the shrub growing amongst the stones.
Surely that'd continue to grow and just be a nuisance.
Possibly grow over your pin or at least push it sideways.
Nice looking country.

The land it is growing on is a nature preserve. I specifically asked the managers of the preserve about whether I could cut the cedar up into kindling, but knew in advance what the answer would most likely be - which it was. Since I was depending upon them to allow me access to search for various other 19th-century survey corners that have not been well perpetuated in the public records, I wasn't in a position to argue. I trimmed a few dead branches to clear the area around the mound for access, but that was as far as permission extended.
I can understand that.
I did a survey in a world heritage area and was very careful about the 'pruning' I did to traverse the boundaries.

An L1 chicken bucket......didn't know there was such a thing. 😎
I still remember getting my chicken bucket with the battery on the end of a 2 meter fiber glass pole, got rid of that pole, I had a short one made up with the battery on the top, quick release for the battery and the bucket, but it was L1/L2 with a radio and all.
L1 wouldn't be much use for me out here far from CORS stations.
A place that wouldn't let you cut a cedar?? I'm going back to bed!

What I do is use my L1/L2 receivers to connect to the CORS network and derive NAD83 coordinates of a few control points (via OPUS) with uncertainties of 3mm or less (standard error) and the project is surveyed from those points. It works very well.

The cedar canopy is part of the reason for the preserve since it's habit for endangered species like the Golden-Cheeked Warbler. The system of placing rough canyon lands like that ranch into conservation reserves was part of a comprehensive plan for protecting the species.

I heard there use to be a similar reserve in LaGrange, TX. If I remember correctly it was for the protection of the Small Breasted Mattress Thrasher species.
I hear it's fine, if you've got the time.....
