Iron Pin vs Property Corner

An iron pin is a kind of monument. The property corner is the legal point, whether or not the pin is still in the ground.

Surveyors set pins to witness the corner. Pins bend, get pulled, or get buried by fill. The corner is the point the plat describes.

A second pin nearby may be an offset or a neighbor's marker. The cap and the survey matter.

The mix-up to avoid

Finding metal with a detector is a clue, not a survey.

Open Platbookmapper and pick the county that taxes the land. Use that viewer to get the parcel ID, then match it to the recorded plat if you need the easements and lot numbers.
