About this map

Saint Helena Sound dominates this coastal landscape where the Combahee River and Ashepoo River meet the Atlantic. The intricate network of tidal creeks and marshes defines the geography, separating large landmasses like Morgan Island and Hutchinson Island from the mainland. The map captures the development patterns of Saint Helena Island, showing the transition from established settlements like Coffin Point to more modern residential developments such as Cedar Reef Villas and Nautical Watch Villas on Harbor Island.

Genealogists and local historians can locate specific landmarks including Coffin Point Cem and Big House Cem. The road network, including Us-21 and various residential drives like Sea Pines Dr and Coffin Point Rd, provides a clear view of the island's accessibility and shoreline infrastructure. The presence of numerous banks and spits, such as Combahee Bank and Marsh Island Spit, highlights the shifting coastal environment of this South Carolina Lowcountry region.
