Location and Position in Archaeology: Revisiting the Original Association of a Folsom Point with Bison Ribs

Abstract

The proveniences (locations) of artifacts have long been critically important to archaeological interpretation. Although of major importance to site formation studies, positional attributes of artifacts (e.g., orientation, dip, which side is up) are seldom mentioned. When discovered in 1927, the in situ association of a Folsom projectile point with two ribs of a Pleistocene form of bison was interpreted as indicative of the contemporaneity of the three items, and thus was taken as evidence for the Pleistocene age of humans in North America. The locational and positional attributes of the two ribs and the point relative to one another suggest it is improbable that the point was deposited simultaneously with the two ribs as a result of it being embedded in the animal's flank, which is not to say the three items are not depositionally and temporally associated. Previously unmentioned positional attributes of the items making up the original Folsom association exemplify the importance of such attributes. New understanding of the original association underscores that actualistic research is required to identify the kinds of positional attributes important to questions regarding site formation and site structure.
