Bays and Sounds in North Carolina and Virginia, USA37.2N 76W
Sediments cloud two large sounds by the coast of North Carolina, separated from the Atlantic Ocean by a chain of low-laying, sandy barrier islands known as the Outer Banks. The light green sound is Pamlico Sound, and the greyish brown sound above it is Albemarle Sound.
The former is the largest lagoon along the east coast of the USA, with a length of 129 km (80 mi) and a width that ranges from 24 to 48 km (15 to 30 miles). The sediments in the sound come from rivers such as the Neuse and the Pamlico.
Visible to the north of the two sounds, in the upper right quadrant, is Cape Charles, a headland in Northampton County, Virginia. It forms the northern side of the entrance to the Chesapeake Bay. Cape Henry, which forms the southern side of the entrance to the Chesapeake Bay, and Cape Charles are collectively known as the Virginia Capes.
