Survey Mark, Fort Pickens, Penscola, FL.
A survey mark is placed to mark key survey points on the Earth’s surface. They are used in geodetic and land surveying. The most common geodetic survey marks are cast metal disks with stamped legends on their face set in rock ledges, embedded in the tops of concrete pillars, or affixed to the tops of pipes that have been sunk into the ground. These marks are intended to be permanent, and disturbing them is generally prohibited by federal and state law. This is a reset mark, a station mark that had been disturbed or destroyed.
