Description:
The Allen Site in southwestern Nebraska has nurtured the interest of archaeologists and paleontologists with abundant signs of a long history of human, animal, and environmental activity. Douglas Bamforth focuses primarily on Paleoindian land use represented by the Allen Site and the adjacent smalle
