Dust Bowl &
The Dirty Thirties - In the 1930s, in the Midwest, across the Great Plains, disaster struck. There were several droughts, one on top of the other. Farms were just recovering when yet another drought hit. The crops died in the fields. That created a new problem - dust storms. Once the crops died, there was nothing to hold the soil in place. Topsoil blew away in huge dust storms.
