A large part of Hatteras Island, Outer Banks, North Carolina, is salt marsh. This picture was taken in Buxton, Dare County, on December 6, 2008, at high tide. Wetlands of this sorts are rich with life both permanent and just passing through. There is a population of Cottonmouth Water Moccasins, for instance, and many kinds of dragonflies, turtles, herons, mockingbirds, and plants that thrive in this type of environment. It is a precious part of the ecosystem.
