Dust Bowl of the 1930s

This example is even better as it has much more to do with human behavior, and also lasted for 6 years... It's a long long period of dust winds.


"The Dust Bowl phenomenon lasted during a drought in the Great Plains from 1930-36. After the dust had settled, it was shown that farming practices in the region were irresponsible with crop rotation, deep plowing, and erosion prevention. On numerous occasions during the dust clouds, the sky would turn black by day as far East as Washington DC. Dirt fell like snow in Chicago. The winter of 1934 red snow fell in the Northeast. And on April 24, 1935, the day became known as Black Sunday."
