During Baum's short stay in Aberdeen, the dissemination of myths about the plentiful West continued. However, the West, instead of being a wonderland, turned into a wasteland because of a drought and a depression. In 1891, Baum moved his family from South Dakota to Chicago. At that time, Chicago was getting ready for the World's Columbian Exposition in 1893. Scholar Laura Barrett stated that Chicago was "considerably more akin to Oz than to Kansas". After discovering that the myths about the West's incalculable riches were baseless, Baum created "an extension of the American frontier in Oz". In many respects, Baum's creation is similar to the actual frontier save for the fact that the West was still undeveloped at the time. The Munchkins Dorothy encounters at the beginning of the novel represent farmers, as do the Winkies she later meets.
