About this map

Cat Island dominates the northern reaches of this coastal survey, serving as a critical navigation landmark where Mississippi Sound meets the Cat Island Channel. The 1890s-era topography reveals a low-lying archipelago including Sundown Island and Brush Island, highlighting the intricate network of tidal waterways such as Grand Pass and Deep Pass that define the eastern edges of St. Bernard Parish.

A key maritime feature is the Cat Island Light, positioned on the western tip of the island near West Point. The detailed shoreline mapping around Spit Cove and Oyster Bay illustrates the dynamic nature of these barrier islands and marshlands before twentieth-century coastal changes. This survey by the U.S. Coast and Geodetic Survey provides an essential record of the Louisiana and Mississippi coastline's configuration at the end of the nineteenth century.
