Abstract En

"Swan Point in central Alaska contains the oldest recognized human occupation in Alaska (Cultural Zone 4b [CZ4b]), dating to circa 14,000 cal BP. This component consists of a microblade and burin industry with clear technological ties to the Siberian Upper Paleolithic Diuktai Culture. Through the systematic use of the Yubetsu method for the production of microblades, Swan Point is technologically more similar to Siberian microblade sites than to later-age (Denali complex) microblade sites in Alaska. The Yubetsu method is the hallmark of the Diuktai Culture, and in Alaska, Swan Point CZ4b is the only component with systematic production of microblades using the Yubetsu method. Other late Pleistocene and Holocene microblade sites in Alaska have an industry based on Campus-style, conical, or tabular microblade cores. Analysis of the collection furthers our understanding of how CZ4b relates to previous Siberian Diuktai-related assemblages and to later Alaskan Denali-related sites. We interpret the CZ4b component as representing a brief single event that has major cultural and technological implications for the early colonization process of North America." (source éditeur)
