[:triangulation station:Triangulation station]s often have ["reference mark"]s associated with them. ["NGS"] recovery reports of a triangulation station involve looking not only for it, but also any reference marks and the ["azimuth mark"]. Usually at least one of these is fairly obvious and that will give you a start on finding the others.

The measurements between the triangulation station and the reference marks are almost always given in what's called the ["box score"]. The box score gives the ["azimuth"] from the triangulation station to each reference mark in the format dddmmss.s but using just ddd part is sufficient for hunting.

It helps to have a compass that reads to the nearest degree, but the most precise thing you will be using is the tape measure, so depend mainly on it.
