crafters Posted February 29, 2004 Share Posted February 29, 2004 Yesterday we went on a day-long benchmark hunt in Junction City, GA. And to start off, this was our first find! Just terrible condition. We went on from there to discover that many of the other markers were missing, and possibly destroyed. We then found this great find (CM1581 Triangulation Station) and managed to locate each reference point. We then went on to look for CM1576 Traverse/Triangulation Station We did locate the station, but this is what we found: Not only was the station broken from the base and sitting on the ground, but it was on the wrong side of the tracks. The location of the reference marker was covered with gravel. Has anyone else ever seen anything like this? Just one sitting on the gound or in worse condition? crafters Quote Link to comment
+Kewaneh & Shark Posted March 1, 2004 Share Posted March 1, 2004 Yes. It happens. I've found marks in both conditions that you've described and in other forms of natural and manmade deterioration. Any time a surveyor leaves a mark out in the public domain, there is the inherent risk that is may get damaged. (It's very similar to placing a cache and hoping it doesn't get bothered. Sometimes it does.) In my area, which is largely agricultural, many disks get damaged or destroyed by farm equipment. The farmers (or the workers) do not intend to do it, as most farmers know the importance of the marks. But being set next to the fields, after 50 or 60 years, they're bound to get covered, bumped, scraped, or completely removed. Some are well protected and do remain in perfect condition too. It's frustrating to find marks that have been damaged, but they make the marks that are in good condition that much more important, and more fun to find. Quote Link to comment
+FSU*Noles Posted March 1, 2004 Share Posted March 1, 2004 I just found this one today that was munched up pretty well - besides the big chunk that appears to be missing from a snowplow or something, the rest of it was pretty well eroded away. Anyone know if it's worth reporting to the NGS for replacement, or is it not far enough gone yet? Curiously yours, -Ken Link to QP0027 Quote Link to comment
ArtMan Posted March 1, 2004 Share Posted March 1, 2004 Anyone know if it's worth reporting to the NGS for replacement, or is it not far enough gone yet? Since the last recovery report, in 1974, identified this mark as being in 'good' condition, it certainly would be worthwhile to update its status with NGS. In addition, since this mark was apparently set by the state dept. of transportation, it might be useful to notify that agency as well, in case they are not aware of the mark's condition. -ArtMan- Quote Link to comment
Dan Vull Posted March 5, 2004 Share Posted March 5, 2004 That does happen. We were setting geodetic control in Korea in 1982, we dug the holes and stamped the marks and set a few beautiful monuments. The next day we wnet to check on the concrete and two of the marks ad been popped off and one had be sliced by a grader. So goes the stories of Mr. Murphy's control party. Quote Link to comment
