Cargill Salt Ponds in San Francisco

This is an amazing Google Maps view of the Cargill Salt Ponds outside of San Francisco. The reason it has so many different colors and stands out in Google Maps is because of all the algae that is growing in the ponds.

According to SouthBay Restoration these ponds will be reverting back to wetlands soon.  You can go visit the ponds if you want to see them before they turn back into the pre-developed wet lands - check out the directions for visiting the SouthBay at their site.

In coming years, the shores of San Francisco Bay south of the San Mateo Bridge will begin to look a bit more like their former, pre-developed selves. The South Bay Salt Pond Restoration Project will be converting several clusters of salt evaporation ponds...

If you want to see them from the sky you probably will need to charter a flight, or hope you can get a good view from a flight coming into San Francisco Airport.
