Thanks for this Benchmark lesson! I feel informed! I've found 10 to date, including: 1 Triangulation Station, 1 Monument, 1 Elevated Tank, 1 Vertical Control Disk, 5 general Benchmark disks, and 1 with unspecified type. I didn't know what all that ment before, but now I do!
I'm interested in finding these, mostly because most of them were set almost 80 years ago! Whenever we go caching somewhere, I look up the local benchmarks and load the LOC file into my GPSr. If there's a BM close to a cache, we'll try to find it! I just wish you could upload a GPX file with the type of BM and NGS description instead of just the coords. That would be nice. Also, I wish Groundspeak would promote benchmark hunting a little more. Maybe have a 'Caches Found' score/number, a separte 'Benchmarks Found' score/number, and then a 'Total Found' score/number.
Thanks again for the information!
