Having visited the area around Canyon de Chelly, I was impressed by the destitution of the indian reservations, the homes, the barren landscape and most of all the people. I would think that you could do wonders in portraying the present day reality of the Native Americans. I have a friend who is Seminole and his ancestors were involved in the "Trail of Tears". The clothing and the faces of these people is not dissimilar to that portrayed in the work of Edward Curtis.
I would love to see what you could do with a project along these lines.
