Infrared film helps accentuate plant growth and sediment accumulations in this near-vertical photograph of the numerous mouths of the Irrawaddy River in western Burma. The Irrawaddy Delta, one of the world's great rice-producing regions, consists of fertile river mud and sand deposited during the last 2 million years. The deep reds and violets at the southern end of the multichanneled delta (top of photo) reflect large mangrove forests. The light blues show the sediment plumes within the stream channels extending southward into the Andaman Sea. Image courtesy of NASA.
