Colourful Salt Ponds...

This unusual sight can be seen in the San Francisco Bay where artificial pond water evaporates and leaves only crystallized salt, coloured algae and micro-organisms. Ponds with low or medium salinity have a green or pink colour and as the salinity increases, the water takes on a more reddish pigment. In addition, the weather also influences the colour of the body of water as more rain makes the water more transparent.
