Bamboo Island and Smith Pt anchor this maritime survey of the mouth of the Potomac River at its confluence with the Chesapeake Bay. This bathymetric-topographic study captures the complex underwater landscape and shifting shorelines that define this coastal boundary between Virginia and Maryland. Significant portions of the map are dedicated to the depth contours of the bay, revealing the subaqueous terrain of the Indefinite Bdy that separates Northumberland Co from its neighbors across the water. The presence of a Light at the point underscores the area's importance for coastal navigation. This edition reflects the environment as it appeared in the late 1960s, with bathymetric data integrated to show the relationship between the low-lying coastal land and the surrounding waters.
