Geodetic control survey points support the production of consistent and spatial accurate data for surveying and mapping. Permanent geodetic monuments provide a consistent coordinate system and serve as the basis for computing lengths and distances between relative positions.

The full "station" list is here:

(Hackensack is about midway through the document).
It would interesting to know how many are remaining.
Benchmark hunting

Surveyors use these benchmarks as reference points when doing land surveys.
