The Dust Bowl: the ecological disaster within the larger disaster of the Great Depression. It’s a story that generations of Americans have come to know through John Steinbeck's classic novel, The Grapes of Wrath and Dorothea Lange's unforgettable photos of migrant families struggling on the road to make a living in Depression-torn California.  In this episode, Adam talks to two prize-winning historians, Linda Gordon, author of a biography of Dorothea Lange, and Sarah Phillips, an expert on the environment and politics in the twentieth century and asks what the dust bowl tells us about the American Dream.
