I've found one of your markers.
Yesterday, I got a call from a local surveyor asking about a marker with my professional identification on it that he had found in the course of surveying a 100 acre tract that once upon a time in the early 20th century was one big cotton field. He described the locality as being at the intersection of two state highways, which placed the marker in question in the general vicinity of where I had made several surveys in the past, but none of which were actually at the intersection.
After a bit more Q and A, I figured out that it was probably a marker that I’d set in the course of a survey of the site for a new school nearly twenty years ago. The surveyor was able to tell me that the identifying number on the aluminum-capped monument he’d found was “222”, so I dug out the map of the project from the file drawer and looked for Rod and Cap No. 222.
I sent him a copy of the map, the listing of the state plane coordinates of all of the markers shown upon it, including several right-of-way markers that have most likely since been destroyed. Nearly twenty years later, it turned out the the marker’s coordinates in the Texas Coordinate System of 1983 remained at current epoch within 0.10 ft. of those that I’d determined in 1998 by connection to a network of L1 GPS vectors I surveyed that began at the Austin CORS and ran in segments for a total airline distance of about 26 miles to Rod and Cap No. 222.
Digging further into the file, I found the report I’d written that gave what I thought were some useful explanations and I passed that along, too. It was interesting to see the form of report that I wrote years ago (a style that has evolved over the years since) and gratifying to see that I’d laid out the rationales for the determinations I’d made in a way that still made sense.
There was also a metes and bounds description that was prepared from the work that actually does appear in the public record (and that does describe Rod and Cap No. 222).
In case anyone is interested, I’ve attached copies of the map, Star*Net listing, report, and written description that together make an account of the work.
