Man-Made Salt Ponds of San Francisco

The northern shores of San Francisco Bay are known for their stunning salt ponds. The variable concentrations of algea, which create a breeding ground for brine shrimp as salinity increases, causes these saltwater evaporation ponds to go from pale green to bright red. These photo sets on flickr document this controlled phenomenon with incredibly graphic results. Had to share it. Enjoy!

There’s also Robert Campbell’s amazing aerial shots of these, although small, on his website.
