This project supports the dissertation research by Co PI Joshua Reuther. The research supported will complete laboratory analyses on aeolian geologic records of dune formation and deflation in the Tanana river basin in order to reconstruct the terrestrial paleoenvironment during the end of the Pleistocene and early Holocene. This research is particularly important in light of the 11,500 yo child creation found at the renamed Upward Sun River site in the Tanana Valley in 2010. The reconstruction of the paleoenvironment will give the archeologist working in this region a better sense of the social and cultural adaptations that they are uncovering for this time period. In addition, the research is important because it will give a more complete picture of how the environment was changing during this critical period of human migration into North America.

该项目支持共同PI约书亚的论文研究。 所支持的研究将完成对塔纳纳河流域沙丘形成和放气的风沙地质记录的实验室分析，以重建更新世末和全新世早期的陆地古环境。鉴于2010年在塔纳纳山谷更名为向上太阳河的遗址发现了11,500名yo儿童，这项研究尤为重要。古环境的重建将使在该地区工作的考古学家更好地了解他们在这一时期发现的社会和文化适应。此外，这项研究很重要，因为它将更全面地了解在人类迁移到北美的这一关键时期，环境是如何变化的。
