Brighter, lighter cultivated field patterns differentiate the slightly elevated land from the coastal swamp land in this color infrared photograph. The deeper reds designate dense vegetation (mainly forests) in this part of the Atchafalaya drainage basin. U.S. Highway 90 crosses the elevated terrain, and several tributaries of the Atchafalaya River and its canals, including a small section of the Intracoastal Waterway, appear as darker features at various locations. Vermilion Bay and West Cote Blanche Bay lie north of March Island (upper left corner). Two white smoke plumes are visible south of the Intracoastal Waterway between Vermilion Bay and White Lake to its west (near the top center of the photograph).
