A North American perspective on the Volgu Biface Cache from Upper Paleolithic France and its relationship to the "Solutrean Hypothesis" for Clovis origins.

The "Solutrean hypothesis" for the origins of the North American Clovis Culture posits that early North American colonizers were direct descendants of European populations that migrated across the North Atlantic during the European Upper Paleolithic. The evidential basis for this model rests largely on proposed technological and behavioral similarities shared by the North American Clovis archaeological culture and the French and Iberian Solutrean archaeological culture. The caching of stone tools by both cultures is one of the specific behavioral correlates put forth by proponents in support of the hypothesis. While more than two dozen Clovis caches have been identified, Volgu is the only Solutrean cache identified at this time. Volgu consists of at least 15 exquisitely manufactured bifacial stone tools interpreted as an artifact cache or ritual deposit, and the artifacts themselves have long been considered exemplary of the most refined Solutrean bifacial technology. This paper reports the results of applying methods developed for the comparative analysis of the relatively more abundant caches of Clovis materials in North America to this apparently singular Solutrean cache. In addition to providing a window into Solutrean technology and perhaps into Upper Paleolithic ritual behavior, this comparison of Clovis and Solutrean assemblages serves to test one of the tangible archaeological implications of the "Solutrean hypothesis" by evaluating the technological and behavioral equivalence of Solutrean and Clovis artifact caching. The hypothesized historical connection is evaluated based on the attributes of the caches themselves, the evidence for geographic and temporal continuity in caching between the two cultures, and the proposed uniqueness of this behavior to Solutrean and Clovis. Results from the comparison of Volgu to Clovis caches indicate that they are divergent with regard to a number of important attributes and appear to represent neither equivalent behaviors nor a historical connection.
