About this map

Maple Marsh dominates the northern reaches of this coastal landscape, where the interplay of land and water is defined by a network of drainage and transport canals. The Intracoastal Waterway cuts a straight path through the wetlands, separating the marsh from the complex island and bay systems to the south. This orthophotomap, produced in 1979, reveals the industrial footprint of the era, specifically the Grand Lake Oil and Gas Field and the Mallard Bay Oil and Gas Field.

Remote settlements like Mallard are situated alongside natural features such as Oak Island and Flat Prairie Island. The intricate hydrology of the area is highlighted by Lake Monzelum, Willow Lake, and the winding Snake Bayou, which contrast with engineered features like the Lulu Canal and Gueyban Ditch. This document provides a clear look at the coastal geography of Cameron Parish before further decades of shoreline change.
