About this map

The low-lying delta of Plaquemines Parish unfolds as a complex network of marshland and waterways in this 2020 survey. Prominent landmasses like Goose Island and Spanish Island are surrounded by a labyrinth of named passes and ponds, reflecting the fluid geography of the Mississippi River's mouth. The nomenclature reveals a mix of family-named landmarks and descriptive nautical features, such as John Johnson Pass and the somberly named Dead Women Pass.

This aquatic landscape is defined by the constant movement of water through channels like Main Pass and Japan Pass. Small, sheltered water bodies including Washington Pond and Joe Dennis Pond highlight the intricate fragmentation of the coastline. For the researcher, the map captures the late-stage deltaic environment, where tidal flows and sediment transport dictate the shape of features like Brant Island and the sprawling Major Outside Pond.
