1919 Map of The Jetties

USGS Topo · Published 1919

About this map

Morris Island and its northern tip at Cummings Point define the coastal landscape of this 1918 compilation. The map focuses on the hydraulic engineering of the harbor entrance, specifically the diverging paths of the North Jetty and South Jetty as they extend into the Atlantic Ocean. These massive stone structures, managed by the Corps of Engineers, were critical for maintaining the shipping channel. The survey provides a clear view of the bathymetry and shifting shoals surrounding these artificial landmarks, which were essential for navigation near Fort Moultrie during the early twentieth century. Because the map was produced in cooperation with the War Department, it emphasizes the maritime infrastructure and underwater contours that shaped the approach to the historic harbor.
