Lanceolate points, formerly called “Yuma,” but now designated by specific type names such as Plainview, Milnesand, Eden, Browns Valley, and others, seem to have been various expressions of a common pattern or tradition that has been called "Piano" by Jennings (Griffin 1957: 23). The Piano tradition in the West represents an ancient hunting stage of culture that followed an earlier stage manifested by the paleo-Indians who used fluted points and hunted elephants of types now extinct.
