The above image shows a 60-kilometer stretch of the Yangtze River in China. In the image, one can see the Xiling Gorge, which is the easternmost of the three big gorges along the Yangtze. The construction site of the Three Gorges Dam, slated to be the world largest, sits on the left-hand side of the image along the big bend in the river. The dam is being built in part to control flooding along the Yangtze.This image was acquired on July 20, 2000.
