This color infrared photograph of the Imperial Valley in southern California features a well-organized and well-managed crop producing landscape, shown by the large amount of red, which, on infrared film, denotes green foliage. The angular field patterns are interrupted by canals, small cities, and towns. The easily recognized field patterns stop abruptly at the U.S.-Mexico border. Visible are the Sand Hills, a lighter landform that parallels the Chocolate Mountains just east of the Sand Hills, and the Salton Sea, the black feature at the top of the photograph.
