1954 Map of Southwest Pass

About this map

The Southwest Pass serves as the dominant navigational corridor through the Mississippi River delta, as captured in this mid-century survey. The landscape is a complex of wetlands and secondary waterways, including Tom Loar Pass and William Pass, which cut through the marsh toward larger bodies of water like Zinzin Bay and Dixon Bay. Inland features such as Bob Taylors Pond and family-named bayous like Sullivan Bayou suggest a long history of local use for fishing and navigation before more intensive modern engineering.
