Chesapeake Bay dominates this maritime expanse, serving as the primary geographic feature of the quadrangle. As an "All Water" survey, the map focuses on the complex convergence of three Maryland county boundaries submerged within the bay's open waters. The intersection of St. Mary's Co Dorchester Co, Dorchester Co Somerset Co, and St. Mary's Co Somerset Co defines the navigational and political divisions of this aquatic territory. For researchers, this document clarifies the exact coordinates where Dorchester, St. Mary's, and Somerset counties meet, providing an essential record of modern Maryland water boundaries and jurisdictional limits away from the immediate shoreline.
