摘要

在一万六千历年以前，从伊利湖、休伦湖和密歇根湖所在的盆地的冰块中流出的冰川融水雕刻出了广阔的沙质平原，上面有无数的壶湖、砾石山和以前的河道。这些提供了一个马赛克沼泽，开放的草本植被，和森林维持多样性的食草动物。这个丰富的生态系统是在不同时期使用不同石器组合的觅食群体的家园。来自贝尔森遗址的一个小组合，完全由来自西南235公里处的阿提卡燧石组成，显示出典型的克洛维斯双面还原和基底制备技术。目前，它是西北地区五大湖地区最常见的这种现象。如果是这样，它应该可以追溯到大约13000年以前。进一步的研究将更好地表征工具工业，并直接确定其时代和生态背景。

The Belson Site: A Paleoindian Campsite on the Outwash Plains of the Central Great Lakes

ABSTRACT By 16,000 calendar years ago, glacial melt waters from the ice masses in the basins which would hold lakes Erie, Huron, and Michigan had sculpted vast sandy plains with innumerable kettle lakes, gravel hills, and former channels. These provided a mosaic of marshes, open herbaceous vegetation, and patches of forest sustaining a diversity of herbivores. This rich ecosystem was the home of forager groups using different stone tool assemblages at different times. A small assemblage from the Belson site, made entirely on Attica chert from sources 235 km to the southwest, manifests characteristic Clovis techniques of biface reduction and basal preparation. At present it is the northwestern-most such occurrence in the Great Lakes region. If so, it should date about 13,000 calendar years ago. Further research will better characterize the tool industry and directly establish its age and ecological context.

期刊介绍： PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
