About this map

Lower Atchafalaya River water traffic and industrial activity define this coastal Louisiana landscape as it appeared in the 1970s. The map captures a shifting environment where the river meets the Atchafalaya Bay, revealing the complex network of natural and man-made waterways essential to the region's economy. Numerous Canal and Pipeline cuts, such as the P L Canal, crisscross the marshy islands, illustrating the intensity of energy exploration in the Mississippi Delta.

Remote infrastructure is marked by several Drill Holes located on Shell Island and near Deer Island Bayou. The indefinite boundary between St. Mary and Terrebonne Parish runs through these wetlands, crossing Deer Island and Plumb Island Point. For the researcher, the map documents the exact positioning of these industrial landmarks and the surrounding shoreline features like East Bay and Little Hog Bayou before later decades of coastal change.
