Benchmark / bench·mark (bench'märk')

Using your GPS unit and/or written directions provided by NGS (National Geodetic Survey), which are available for review by the public, you can seek out NGS survey markers and other items that have been marked in the USA.

At the top of peaks or in a village square, you probably walk by at least one every day.
