The Dust Bowl of the 1930s was a period of severe dust storms and drought in the central United States. It mostly affected the southern Great Plains, with dust storms and drought exacerbating the Great Depression. Over 100 million acres of land were affected, forcing many farmers to abandon their land. Many migrated west to California seeking work, becoming known as "Okies." The Dust Bowl had long-term impacts - counties that experienced high levels of erosion saw declines in agricultural land values of over 25% that were still not fully recovered decades later. Artists like photographers and musicians documented the Dust Bowl, helping publicize the crisis through iconic images like Dorothea Lange's "Destitute Pea Pickers."
