About this map

South Pass cuts a distinct channel through the Mississippi River Delta toward the Gulf of Mexico in this mid-1930s survey. The landscape is defined by an intricate network of waterways including Dennis Pass, Loomis Pass, and Wright Pass, which separate numerous ponds and marshy islands. At the southern tip, the settlement of Port Eads serves as a vital maritime outpost, supported by the Pilot Sta and the South Pass L H lighthouse.

Detailed survey work by the State of Louisiana and federal agencies highlights the engineered navigation of the era, specifically the East Jetty and West Jetty that maintain the channel's depth. Named features like Valentiers Pond, Morgan Pond, and Johnson Pond reveal a localized geography of the delta before significant modern coastal erosion. The presence of the Minnesota and Louisiana labels near the northern boundary suggests specific land claims or stations in this transition zone between East Bay and Garden Island Bay.
