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 rural area outside Boise City, Oklahoma, the population dropped 40% with 1,642 small farmers and their families pulling up stakes. The Dust Bowl exodus was the largest migration in American history. By 1940, 2.5 million people had moved out of the Plains states; of those, 200,000 moved to California. When they reached the border, they did not receive a warm welcome as described in this 1935 excerpt from Collierâs magazine.
