Figure 2.43 The relocation diffusion of Upland Southern hill folk from Appalachia to western Washington. Each dot represents the former home of an individual or family that migrated to the Upper Cowlitz River basin in the Cascade Mountains of Washington State between 1884 and 1937. Some 3000 descendants of these migrants lived in the Cowlitz area by 1940. What does the high degree of clustering of the sources of the migrants and subsequent clustering in Washington suggest about the processes of folk migrations? How should we interpret their choices of familiar terrain and vegetation for a new home? Why might members of a folk society who migrate choose a new land similar to the old one?
