The Nutritional Context of the Pueblo III Depopulation of the Northern San Juan: Too much maize?
Author(s): R. Matson
The abandonment of the Four Corners area is a longstanding problem in
archaeology. Recent work has shown that the terminal occupation was
concentrated into a limited number of large defensive sites. This resulted in an
extreme emphasis on maize, which was untenable because of maize's low
amounts of Lysine and Tryptophan. I describe the processes that led to this
settlement pattern and the evidence for this diet. I then explain how the
combination of the settlement pattern and the extreme reliance on maize resulted
in a nutritionally fragile situation that collapsed. I end with a few thoughts on
