About this map

Pea Patch Island and the strategic military works guarding the Delaware River define this coastal landscape in the early 1990s. At the heart of the channel, Fort Delaware stands as a focal point for the regional defense system, complemented by Fort Mott and Finns Point National Cemetery on the New Jersey shore. The map illustrates a complex network of waterways and managed lands, including the Chesapeake and Delaware Canal and the Supawna Meadows National Wildlife Refuge.

Settlement patterns concentrate in historic riverfront communities like Delaware City and Port Penn, while the surrounding terrain is a mosaic of marshes and reclaimed points. The inclusion of Fort Elfsborg and Sinnickson Landing provides significant points of interest for those tracing the colonial and maritime history of New Castle and Salem counties. The land-use transition from industrial sites like the Refinery to the protected Augustine State Wildlife Management Area reflects the evolving 20th-century character of the Delaware estuary.
