Southwest Pass forms the narrow, engineered corridor at the very tip of the Mississippi River delta, serving as a critical maritime gateway to the Gulf of Mexico. The isolated settlement of Burrwood stands as a lonely outpost amidst the marshy terrain, connected to the river channel by the Sanitary Canal and Burrwood Bayou. Navigational infrastructure dominates this 1935 field examination, with the Southwest Pass L. H. and the Pilot Sta providing essential guidance for vessels navigating the shifting silt and currents. Long stretches of the West Jetty and East Jetty, reinforced by a Protection Wall, define the channel, while surrounding features like Lighthouse Bayou and Mud Bay illustrate the fragile, water-bound geography of Plaquemines Parish before modern coastal changes.
