About this map

The coastal defense landscape of the Gulf of Mexico is prominently displayed in this military reconnaissance, highlighting the strategic convergence of Fort Barrancas Military Reservation and the U.S. Navy Yard. This 1921 survey illustrates the complex maritime geography of the Alabama-Florida border, where the Perdido Bay and Bayou Grande separate the mainland from the protective barrier of Santa Rosa Island. The map meticulously details the harbor entrances at Caucus Shoal and Middle Shoal, guarded by the historic fortifications of Ft. Barrancas, Ft. Pickens, and Ft. Mc.Rae.

On the mainland, the industrial and civilian character of the era is evident in the settlements of Warrington, Woolsey, and Millview. Transportation networks include the L. & N. R. R. and the Terminal Ry., which linked these coastal communities to the interior. Numerous named points like Du Pont Pt and Tarklin Pt dot the shoreline, providing essential landmarks for navigation through Tarklin Bay and the winding Ono Island River.
