Until the calamity of the BP Deepwater Horizon oil spill in the Gulf of Mexico and recent catastrophic hurricanes, the American Gulf Coast-a dynamic region of marshes, swamps, bayous, beaches, and hardwood forests-largely evaded national consciousness. In Terra Incognita: Photographs of America's Third Coast, photographer Richard Sexton explores this oft overlooked but now extremely endangered landscape in a sequence of dramatic duotone photographs. Covering the Gulf Coast from the Mississippi River to the Florida panhandle, Sexton's images of woods and wetlands resonate with spare simplicity and quiet beauty. Panoramas of gnarled trees, vistas of sea and sky, and shorelines dissolving into a misty fog depict the haunting terrain of the gulf coastal plain. This book and these photographs represent a natural miracle now under fearsome assault.
