Image Caption: Linta River delta and dunes, southern Madagascar
Astronauts aboard the International Space Station used a very long lens to shoot this detailed image of the remote Linta River delta zone in southern Madagascar--showing 7.5 miles (12.1 km) of complex shoreline. Waves break far offshore (1.4 mi, 2.25 km) against a long line of coral reefs. A gap in the reef opposite the delta indicates where the river flowed at times of low sea level when the shoreline was far to the southwest of its present position, crossing the lower left corner of the image.
Bright, light-toned dunes cast shadows in the late afternoon sun. These winds build sand dunes by blowing sand out of the Linta River bed (image upper left). The bigger dune field (image upper right) is fed by sand moving from another delta out of the picture right. Just inland, numerous agricultural blocky fields occupy earlier dune fields (image far top right).
