1982 Map of East Of Point Lookout

About this map

Chesapeake Bay dominates this bathymetric study, revealing the complex underwater topography of the Maryland waters. The map focuses on the submerged landscape where the jurisdictional boundary between St Marys Co and Somerset Co runs through the open water. Unlike traditional topographic sheets, this 1982 edition by the National Ocean Survey utilizes tide-coordinated hydrographic data to map depths and shoals. The detail provided captures the shifting nature of the bay floor, showing various depth gradients and the deeper channels that defined maritime transit in the late 20th century. For historians and researchers of the Chesapeake, this sheet serves as a record of the bay's bathymetry before modern coastal changes, documenting the underwater terrain that supported the region’s vital fishing and shipping industries.
