1958 Map of Heron Bay

About this map

Mon Louis Island and the marshy expanses of Heron Bay anchor this coastal landscape, which was updated in the early 1980s to reflect contemporary development. The map details the transition from the mainland to the Gulf, highlighting the essential maritime corridors of the Intracoastal Waterway, Grants Pass, and Herons Pass. Along the southern edge, the western end of Dauphin Island shows established infrastructure such as Bienville Blvd and the Dauphin Island Landing Strip near Pt Isabel. This survey provides a precise look at the shifting shorelines of Portersville Bay and Mississippi Sound, capturing the area before significant modern coastal changes. Smaller features like the Cem near the settlement of Heron Bay and family-named landmarks like Sullivan Bayou offer specific points of interest for genealogists tracing local history along the Mobile County coast.
