Colourful Salt Ponds Are Nature’s Own Art (11 pics)

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.
