About this map

St. Helena Island and its surrounding archipelago define this coastal landscape just after World War II. The map focuses on the complex tidal waterways where the Morgan River and Harbor River converge into the expansive St. Helena Sound. A lone Tower stands on the eastern shore of Hunting Island, likely serving as a crucial navigational aid for vessels navigating the shifting shoals and inlets of the Atlantic Ocean.

Coastal geography dominates the sheet, showing the intricate marshlands and creek systems like Jeffords Creek and Fish Creek that separate Otter Island and Pine Island from the mainland. The presence of 174 leading toward Bay Pt on Edisto Island indicates the early development of modern transportation routes into these sea island communities, reflecting a period when many of these islands remained primarily rural and defined by their natural water boundaries.
