USA – November 10th, 2012

Green sediments create swirled patterns in Pamlico Sound, North Carolina, and along the Outer Banks, the row of low, sandy barrier islands that separate the sound from the Atlantic Ocean. At 129 km (80 mi) long and 24 to 48 km (15 to 30 miles) wide, it is the largest lagoon along the east coast of the USA. Pamlico Sound is linked on the north with Albemarle Sound through Roanoke Sound and Croatan Sound (passages).

Also of interest in this image are the Appalachian Mountains, visible upon opening the full version. The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west. These alternating ridges and valleys are easily discernible as alternating brown and green lines.
