An Archeological and Paleoecological Study of the Late Pleistocene to Early Holocene Occupants of the Lime Caves in Southwestern Alaska

摘要OPP-9414451阿克曼这次考古、地质和古生态调查的重点是最近在阿拉斯加西南部石灰山地区发现的保存条件良好的石灰岩洞穴。对一个洞穴入口的初步采样表明，有两个主要的时间间隔。上层包括骨头、鹿角和石头，底部年代为9500年前，可以与阿拉斯加西部的古北极传统或阿拉斯加中部的德纳利建筑群联系在一起。较低的水平，目前为止只发现动物遗骸，可以追溯到晚更新世(13,000-15,000 BP)。该项目将从这两个地层分区恢复人工和生态数据，以确定全新世和晚更新世人类活动的顺序。更多的工作将被用于采样其他洞穴和天坑，以及附近沼泽和湖泊的取芯。该项目的目标是确定该区域人类存在的年代，并收集数据，为了解当时的环境状况提供依据。*？？

ABSTRACT OPP-9414451 ACKERMAN This archaeological, geological and paleoecological survey will focus on an area of limestone caves with excellent preservation conditions which were recently discovered in the Lime Hills region of Southwestern Alaska. Preliminary sampling of one cave entrance has suggested two major intervals. An upper level contained artifacts of bone, antler and stone with a bottom date of 9500 BP, and can be associated with the Paleoarctic tradition of Western Alaska or the Denali Complex of Central Alaska. The lower level, with only faunal remains found thus far, dates to the Late Pleistocene (13,000 - 15,000 BP). This project will recover artifactual and ecological data from these two stratigraphic divisions to determine the sequence of human occupations during the Holocene and late Pleistocene. Additional efforts will be directed towards sampling other caves and sinkholes as well as the coring of nearby bogs and lakes. The goal of the project is to determine the antiquity of human presence in the region and to collect data that will provide insights into the environmental conditions of those times. *** ??
