About this map

The settlement of Intracoastal City stands as a vital hub for marine and industrial activity at the junction of the Intracoastal Waterway and the Vermilion River. This mid-1970s landscape is defined by its extensive network of navigation channels and drainage infrastructure, including the Miller Island Canal, Freshwater Bayou Canal, and the Vermilion Lock. The map reveals the critical importance of the oil and gas industry to this coastal region, marked by numerous heliports and gas wells scattered across the marshy terrain and gas fields.

Further inland, the community of Esther and the Mouton Cove Cem provide anchors for local history and genealogy. The transition from the higher ground of Palmetto Island and Big Woods Island to the expansive wetlands of Vermilion Bay and Little White Lake is crisscrossed by several boat trails. Aviation history is also represented through private infrastructure like the Sagrera Landing Strip and Roy Lee Landing Strip, reflecting the logistical needs of this water-bound environment.
