This map intends to show the viewer events and places described in the famous John Steinbeck book. We have mapped the Joads' itinerary as shown in "The Grapes of Wrath: Text and Criticism", ed. by Peter Lisca with Kevin Hearle, New York: Penguin, 1997; the Historic Route 66, or, "The Mother Road", where the migrants travelled to California. We have shown the severe wind erosion in the Dust Bowl area, 1935-1940. We intend to add more information that we hope will help us place the Steinbeck work in a concrete geo-political context.
