1979 Map of St Catherines Sound

About this map

St Catherines Island and its surrounding tidal landscape are preserved in this late 1970s bathymetric and topographic study. The map documents a complex network of coastal waterways including the Medway River, North River, and the Intracoastal Waterway, which cuts through the salt marshes. Settlements are sparse in this environment, though Yellow Bluff Fishing Camp appears on Colonels Island, signaling the area's recreational and maritime utility. The southern portion of the sheet is anchored by the Harris Neck National Wildlife Refuge and the southern reaches of the South Newport River. By combining traditional topography with bathymetry, the map details the shifting sands of the Medway Spit and the depths of St Catherines Sound, providing a record of the Georgia coastline before modern environmental changes.
