A brass or aluminum disk placed as a memorial for a surveyor who has passed away. It looks identical to a standard geodetic benchmark or property corner monument but is stamped with the surveyor's name, license number, and lifespan. Professional surveying societies often set these disks at locations significant to the surveyor's career or at their gravesite.

Insider tip
While they look like active control points, final points are strictly ceremonial and are not published in geodetic databases or used for traversing.
