1968 Map of Mound Point

About this map

Marsh Island dominates this coastal survey, serving as a critical sanctuary within the Russell Sage Foundation-Marsh Island State Wildlife Refuge. The landscape is defined by the intricate transition from land to sea, where tidal drainage such as West Branch and East Branch carve through the wetlands. This 1968 revision captures the fragile nature of the Iberia Parish shoreline before significant modern erosion, detailing the extensive Shell Reefs that once buffered the coast from the Gulf of Mexico. To the south, the Shell Keys National Wildlife Refuge marks a string of isolated landmarks, including the prominent Shell Keys. The mapping includes bathymetric data around Mound Point and the entrance to Oyster Bayou, providing a record of the shifting seafloor and coastal geometry during the late 1960s.
