The document discusses the Dust Bowl period of the 1930s when drought and farming practices led to massive dust storms in the Great Plains. It analyzes John Steinbeck's depiction of migrant farmers in The Grapes of Wrath and Dorothea Lange's photographs, finding they exaggerated the experiences of the "Joad family" and other migrants. Statistics show that only about 2% of migrants to California during this period came from the Dust Bowl, with many migrating for other economic reasons, and the migrant experience was more diverse than the novels and photos suggested.
