1919 Map of The Jetties

USGS Topo · Published 1919

About this map

Morris Island and its northernmost tip at Cummings Point anchor this coastal survey, which documents the critical maritime engineering protecting the entrance to Charleston's harbor. Produced in cooperation with the War Department and the Army Corps of Engineers, the map details the massive underwater structures of the North Jetty and South Jetty as they extend into the Atlantic Ocean. These harbor defenses were vital for maintaining navigable channels through the shifting sands of the South Carolina coast. The map provides precise bathymetric data, showing the depth contours off the shore at five, ten, and twenty feet below mean low water. This specialized study focuses on the intersection of land and sea, where man-made infrastructure meets the natural forces of the Atlantic.
