About this map

Saint Helena Island and its surrounding archipelago define this coastal landscape where the Combahee River, Ashepoo River, and Morgan River converge into the Saint Helena Sound. The map reveals a complex network of tidal creeks and islands, from the larger Morgan Island and Hunting Island to smaller landmasses like Butchers Island and Horse Island. Settlement patterns are concentrated along local thoroughfares such as the Sea Island Pkwy, with specific residential clusters at Fripps Point and Coffin Point.

Genealogists and local historians can locate specific sites of interest, including the Coffin Point Cem and Big House Cem, which reflect the long-standing community footprint on the island. The transition from the mainland's marshy fringes to the open Atlantic Ocean is marked by significant sand features like Egg Bank, Oyster Bank, and Pelican Bank. This 2017 survey details the contemporary layout of subdivisions and access roads, including McTeer Dr and Camelot Farms Dr, while documenting the shifting boundaries between Colleton and Beaufort counties.
