I don't know of any written work on the subject, but there is a proliferation of neolithic sites in southern Norway around about the 50m contour line. I have often wondered if the location of these sites might represent the highest level at which certain types of field system/crop regimes were viable, with the higher and lower lands still reserved for hunter-gatherer activities....what kind of level are these sites appearing in Yorkshire and Durham?
