Property corners can be marked with a variety of materials. In the 1800’s, surveyors typically did not carry monuments with them. The surveyors would create a property corner monument using whatever materials were available. This usually meant piling up some rocks or hacking a nearby tree. Other items used in times past were railroad spikes and car axles.

The most common material used today is iron rebar. Other items that might mark property corners include: iron pipes; wooden stakes; poured concrete monuments; cross-cuts or shallow drill holes placed in concrete; and masonry nails driven into asphalt pavement.
