“The Great Depression” was the worst economic period in history and was caused by a stock market crash in 1929. Millions of people lost their jobs and homes as a result and took to begging or stealing as a means of survival. With no money and little hope, people began dancing as a means of escaping the gloom of everyday life.

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.
