Parana and Iguazu rivers, South America
ESA · Download full size image
This ASAR (Advanced Synthetic Aperture Radar) image shows the Parana River flowing north-south and the Iguazu River flowing west-east. The two rivers form parts of the borders between Paraguay (to the west of the Parana) Brazil (west of the Parana north of the Iguazu) and Argentina (south of the Iguazu). Zooming towards the south center part of the image the Iguazu can be seen to thin dramatically. This is caused by the Iguazu Falls: considered to be one of South America's greatest natural wonders they range in height from 60 to 80 m. Two crescents of water are formed in the summer season each 730 m across, though in the winter they merge to form a waterfall 4 km wide. The lighter shading of the land around the falls is roughly the outline of the National Park of Iguazu.
