yellow river (huang he) of china
Another view chosen for many online photo awards!
It is interesting that the Yellow River isn’t yellow in its upper reaches. In its lowest reaches it gets into lots of other colors because of industrial pollution. So it tends to be green in its upper reaches, sort of yellowy brown in the middle and variable as it flows past farms and industrial plants.
Here is a link to a 2006 video report by Jim Yardley of NY Times that tells most of the grim story about the Huang He.
