The Dust Bowl, also known as the Dirty Thirties, was a period of severe dust storms that greatly damaged the ecology and agriculture of the US and Canadian prairies during the 1930s; severe drought and a failure to apply dryland farming methods to prevent wind erosion (the Aeolian processes) caused the phenomenon.
In the 1930s, farmers from the Midwestern Dust Bowl states, especially Oklahoma and Arkansas, began to move to California; 250,000 arrived by 1940, including a third who moved into the San Joaquin Valley, which had a 1930 population of 540,000. During the 1930s, some 2.5 million people left the Plains states. The Modesto Bee on September 30, 2008 reviewed Dust Bowl migration to California. A series of wet years in the 1920s led farmers to believe that the Plains could sustain annual plowing to produce wheat.
