USA’s East Coast from the Appalachians to the Atlantic37.7N 77.3W
Greenish sediments flank the states along the east coast of the USA, from New York and New Jersey (top), to Delaware and Maryland (center), to Virginia and North Carolina (bottom).
The sediments are particularly concentrated in Virginia and North Carolina’s Outer Banks region, a 200-mile (320-km) long string of narrow barrier islands, as they are held in the water between the coast and the islands before flowing into the Atlantic.
Further inland, the brown ridges of the Appalachian Mountains extend northwards towards Canada. West of the range, at the upper left, part of Lake Erie can be seen. Sediments are also present here along its shores.
