About this map

Marsh Island anchors the southern reaches of this mid-century survey, a landscape defined by the expansive waters where Vermilion Bay meets West Cote Blanche Bay. This coastal environment is documented during a period of transition, showing the early infrastructure of the petroleum industry alongside protected conservation lands. Significant offshore features like Terrapin Reef are meticulously marked with markers for piles and oil platforms, reflecting the maritime and industrial activity common to the Louisiana gulf.

The presence of the Russell Sage Foundation State Game Refuge on the marshy northern edge of the island highlights the era's focus on wildlife preservation. Key landmarks such as the Conservation Camp and the small projection of Cypremort Point provide terrestrial reference points for local history researchers tracing the development of this shoreline. Drainage networks, including Bayou Platte and Bird I Bayou, show the natural hydrologic patterns of the wetlands before later modern developments altered many coastal waterways.
