The western author Louis L'Amour was doing research in this field when he unfortunatley passed away. I have talked to several people who have tried to get access to his research, but they have been unsuccessful.
Seeing that info would be a great find, i know from reading his western novels that his research was meticulous, if he said a stream or a cave or any geographic feature was somewhere (in a novel), it is really there - I have followed several of the trails he described while on vacations, every nook & cranny he described is there, including locations with ancient cliff drawings, artifacts, etc.
