Just for everyone's information, this benchmark is NOT the one near GC10R84 Fourteen Mile Creek cache. It has been erroneously logged by several geocachers. The benchmark near the cache has a designation of 18V-T 1969. It was placed out by the MS Highway Department in 1969.
As you geocache, you may run across benchmarks. What you need to always keep in mind, is not all benchmarks will be in the NGS database, which is the one gc.com has listed on their website. Many agencies place out benchmarks, including the MS Highway Department. The NGS database will have some other agencies benchmarks included in their database, if they meet the NGS requirements for inclusion..........however there are going to be as many that do not meet these requirements, than those that do. So you have a good chance of finding a benchmark that is not going to be loggable on gc.com. The one (pic posted) near GC10R84 is not loggable on gc.com
You will need to always read the datasheet, and make sure that the designation inscribed on the benchmark matches what the datasheet says it should.
Hopefully this will help out everyone in the future, and make sure that you are logging the correct benchmark. Benchmarking can be a very enjoyable addition to geocaching.
This is not CP0413
