1971 Map of Pass A Loutre West

About this map

The Mississippi River delta in Plaquemines Parish reveals a complex aquatic landscape of shifting channels and marshland as it appeared in the early 1970s. This orthophotomap, derived from 1971 aerial photography, captures the transition of the river's main flow through the Head of Passes Light where it bifurcates into numerous distributaries. Industrial activity is prominent in this environment, evidenced by the Duck Oil Field and various sludge pits located amongst the wetlands.
