1947 Map of Main Pass
USGS Topo · Published 1947About this map
Breton Sound meets the intricate marshlands of the Mississippi River Delta in this 1947 survey, where a complex network of bayous and ponds defines the Plaquemines Parish coastline. The map illustrates a landscape dominated by shifting water and land, characterized by features like Salle De Danse and Octave Pass. A single man-made landmark, the Duck Club, stands near the edge of the wetlands, suggesting the area's primary use for recreation and hunting during the mid-twentieth century. Natural formations such as Timber Island and Harris Island emerge from the delta, while specific water bodies like Piling Pond, Blackbird Pond, and Speckled Goose Pond highlight the local fauna that once thrived in these tidal reaches. The intricate detail of Flatboat Bayou and Delta Pass shows the navigational challenges of the era before modern land loss significantly altered these shores.
