About this map

The coastal waters of the Gulf of Mexico dominate this orthophotomap, revealing the intensive maritime and industrial activity off the Louisiana coast in the early 1970s. This survey, compiled from high-altitude aerial photography and hydrographic data, captures the industrial footprint of the Block 69 Oil Field and adjacent Oil Field areas. Scattered across the water are numerous offshore platforms and oil wells, demonstrating the scale of mineral extraction in the deltaic region. In the lower corner, the shifting coastal geography is visible through features like Japan Island and the marshy perimeter of Japan Outside Pond. This area is intersected by the notable coastal waterway Dead Women Pass, providing a precise look at the interface between the fragile marsh landscape and the heavy infrastructure required for deep-water energy production during this era.
