1919 Map of The Jetties

About this map

The North Jetty and South Jetty define the hydraulic engineering at the mouth of Charleston Harbor as it stood just after the Great War. This Progressive Military Map, produced by the Corps of Engineers, U. S. Army in cooperation with the U. S. Coast and Geodetic Survey, focuses heavily on coastal bathymetry and the maintenance of maritime navigation channels. The northern tip of Morris Island is visible at the edge of the sheet, anchored by the landmark Cummings Point. Because this is a hydrographic-focused chart, it provides detailed underwater contours for the Atlantic Ocean floor, illustrating the complex shoals and sandbars that the jetties were designed to scour and manage to ensure safe passage for shipping into one of the South's most significant ports.
