1919 Map of The Jetties

USGS Topo · Published 1919

About this map

Morris Island and its northernmost tip at Cummings Point define the coastal boundary of this maritime survey. Produced just after World War I, the map focuses on the man-made engineering of the harbor entrance, specifically the North Jetty and South Jetty extending deep into the Atlantic Ocean. These structures were critical for stabilizing the shipping channels leading into Charleston. The cartography provides detailed bathymetric data, showing the seafloor contours at five, ten, and twenty feet below mean low water. This particular edition was compiled in cooperation with the War Department as a progressive military map, emphasizing the strategic importance of the shoreline and its shifting shoals during the early twentieth century.
