Land Cover of the Mid-Atlantic Coast
The distinctive Mid-Atlantic shoreline is intricately shaped by past glacial action. Long Island is a glacial moraine. Delaware Bay, Chesapeake Bay, and Albermarle and Pamlico Sounds are drowned valleys, carved in a wide coastal plain when sea level was lower, then flooded as ice caps melted. Coastal wetlands and barrier island spits are ever-changing but persistent features.
Slightly higher ground includes large farmland areas of the Delmarva Peninsula and Pamlico Sound. An inticate farmland / forest mosaic extends west to the Fall Line, followed by the somewhat more heavily forested Piedmont.
Coastal port cities, the core of early 19th century urbanization, have spread through suburbanization into nearly unbroken Metro areas from Fredericksburg to Long Island Sound and the Connecticut River Valley.
This map includes all of the coast from the western
edge of Narraganset Bay south to Santee Point in South Carolina.
Coverage includes all of Connecticut, New Jersey, Pennsylvania,
Maryland, and Delaware, along with most of New York, Massachusetts, and
eastern Virginia and North Carolina.
