How would one integrate a geography and a history curriculum in the reading of The Devil's Highway?

I am not a Geography teacher, but I would think that this
excellent and deeply moving book would lend itself well to a discussion of elements of
Geography and History. Certainly investigating the Devil's Highway, and looking at it
from a perspective that analyses desert and the harshness of the conditions there could
easily cover a number of aspects of physical Geography. Yet, in terms of human
Geography, you might want to think about the wider themes of migration and movement of
peoples and the social impact of such trends. This could easily be linked to studying
History by looking at the relationship between the USA and Mexico and other Latin
American countries and thinking about how the inequalities and power differences have
been created, and indeed, how they are sustained today. In short, a bit of creative
thinking could easily turn the study of this excellent text into a multi-disciplinary
project encompassing Sociology, History and Georgraphy as well as
Literature.
