Learn about PIDs, Designations, Types of benchmarks, How to Search for a benchmark online, and How to Log a benchmark. Find out why coordinates on the Datapage aren't always correct. How big is a benchmark? What is a witness post?
Get (most of) your questions answered.
Although this is not required, Good bench mark hunters will post the following items in their benchmark logs.
- Coordinates on your GPS, phone, or other device.
- Elevation reading.
- Close-up photo of the disk, rod, or other bench mark type.
- A second photo from a few feet away showing the mark and the general surroundings/location.
What is a benchmark?
Benchmarks can be found all over the United States. They are used by land surveyors, builders and engineers, map makers, and other professionals who need an accurate answer to the question, "Where?"
Why search for benchmarks?
The interesting thing about benchmarks is that a majority of them are located in plain sight (though largely ignored by the general public). There's a certain excitement to Be the First to Find and document a control point, as well as seeing what others have found.
Where does the benchmark database come from?
In 2000, Geocaching.com imported a snapshot of the ever-changing benchmark database from National Geodetic Survey (NGS), a federal agency within the Department of Commerce. The NGS database contains all sorts of information about these benchmarks.

I hope you enjoy benchmarking as much as I do!
