1954 Map of Cobb Rocks

About this map

The coastal marshlands and open waters of St Marks National Wildlife Refuge dominate this mid-century survey along the Gulf of Mexico. Transitioning from the forested northern boundary into a dense network of tidal inlets, the landscape is defined by the convergence of several freshwater and brackish outlets, including the Pinhook River and Deep Creek. This specific shoreline configuration, where the Wakulla Co Jefferson Co line meets the coast, showcases the intricate drainage patterns of the Florida Panhandle before later development. Mariners and local historians can identify hazards and landmarks across Apalachee Bay, such as the submerged Cobb Rocks, the isolated Grey Mare Rock, and the prominent Big Redfish Point. The chart also marks various offshore platforms and the Pinhook Cut-off, reflecting the era's navigational and coastal infrastructure.
