About this map

Tante Phine Pass and the intricate marshlands of Plaquemines Parish appear here in this 1935 field examination, compiled during the mid-1940s. This survey reveals the complex hydrology of the Mississippi River delta before late-20th-century coastal erosion significantly altered these landforms. The map traces vital waterways like Spanish Pass and Tiger Pass, alongside man-made features such as the Company Canal and Venice Canal, which reflect the early industrial and navigational infrastructure of the region.

Remote coastal features including Yankee Pond, Fleur Pond, and Bog Pond are documented alongside the transition from the interior marshes to the Gulf of Mexico. The presence of labels like Sandy Pt and Sandy Point Bay provides a specific reference for those studying the shifting shoreline of southern Louisiana. This sheet captures a landscape defined by pass, bayou, and canal, providing a primary source for understanding the delta's historical geography.
