This exhibit describes the exodus of the Okies during the Dust Bowl years in 1930s.The Okies fled from the Dust Bowl to California.
The Dust Bowl is a very big storm of dust. This storm destroys the fields, the crops, the houses, the belongings of farmers, everything who are on its way. As a consequence, it becomes impossible to raise crops on the dust-covered land and the people have to tie handkerchiefs over their faces when they go out. So the farmers must go in another land. They went to California.
