Scout03 Posted October 31, 2003 Share Posted October 31, 2003 Hi All, Looking for my first Benchmark. There has been recent construction on roadways and sidewalks in the area. However there is a post that looks almost exactly like the one pictured here: See Post in Lower Right A difference is the post I found has a steel rod down the middle. Is that a "witness post"?? I am looking for Benchmark GG0102 Scout03 Quote Link to comment
+happycycler Posted October 31, 2003 Share Posted October 31, 2003 Great! Another person searching out benchmarks! Welcome to the fun. The object in your photo may be a highway RW (Right-of-Way) marker. I notice that Hwy 72 does run near GG0102 but I have personally not noticed highway RW markers in a city. Everybody loves benchmarks more! Quote Link to comment
+DustyJacket Posted October 31, 2003 Share Posted October 31, 2003 Check for the benchmarks forum thread: Photos of Survey Marks and Witness posts. There are samples of various marks and posts (and trees and buildings and......) as wll as a link to a page of a lot of photos, hosted by yours truley. DustyJacket Not all those that wander are lost. But in my case... Quote Link to comment
+happycycler Posted October 31, 2003 Share Posted October 31, 2003 ...continued... My keyboard stopped working. I was going to mention the photos of witness posts & benchmarks posts--but Dusty beat me to it. Another thing, the benchmark GG0102 has SCALED coordinates. They were taken from a map and therefore may be off. I suggest that you depend more on the description than your GPS. I would start with: quote: ...CEMENTED IN A DRILL HOLE IN A CURB AT THE EAST ENTRANCE TO THE PARK. Then (if necessary) measure your average pace and pace off the other distances that are mentioned in the description. GOOD LUCK and welcome to benchmarking. Everybody loves benchmarks more!

Scout03 Posted October 31, 2003 Author Share Posted October 31, 2003 I did that, I know the size of a pace due playing golf for years. I measured per the description from the monument and the center of the street and found an area that was re-constructed. The square was overhauled recently including curbs, sidewalks etc. in the immediate area of the description. Scout03 Quote Link to comment
Z15 Posted October 31, 2003 Share Posted October 31, 2003 That is definately a highway Right of Way marker. Thats steel re-enforcing you see. Mike Survey Tech (Retired) Quote Link to comment
Snipe33 Posted November 1, 2003 Share Posted November 1, 2003 I started geocaching about 2 months ago and I think I prefer searching for benchmarks. (Well, the disk benchmarks anyways) The benchmarks are definately alot more challenging since the coords are never accurate and you always end up using the descriptions. Sure finding a container of junky toys is fun....but I find it more rewarding to find something that was placed in 1920 that hasn't been logged by any other civilians Snipe33 Quote Link to comment
Z15 Posted November 1, 2003 Share Posted November 1, 2003 I just FOUND a USGS Bench Mark last week that was probably not uncovered in a long time. THe only was to find it was with the position and GPS (WAAS). Turned out to be down a dead end 2 track woods road, was buried under years of old leaves etc. It was in rural wooded area and the only reference was an old fence intersection of which I found a few old rotten posts lying on the ground and measured from the record "T" intersection and hit it with the shovel.
