This project refines reconstructions of subsistence traditions in central Alaska by applying traditional knowledge and isotopic analysis to the interpretation of archaeological hearth remains. Isotopic data from over fifty legacy collections and remains of experimental cooking features will be analyzed to reconstruct past subsistence practices. Experimental and legacy hearth residues will be compared with newly excavated hearths recovered through targeted excavations at two sites in different ecological settings in the middle Tanana Valley. Research will be combined with mentorship and hands-on learning opportunities for Alaska Native youth at summer culture camps. Undergraduate and graduate students as well as one post-doctoral researcher will benefit from field- and lab-based training and educational opportunities.This project employs 1) isotopic and molecular analysis of legacy and experimental hearth remains; 2) targeted excavation at two sites in central Alaska, Swan Point and Niidhaayh Na’; 3) analysis of newly recovered archaeological materials; and 4) interpretation and synthesis of results with community stakeholders. The isotopic, molecular, macrobotanical, and artifactual data collected during this project will be used to reconstruct late Pleistocene and early Holocene subsistence, diet breadth, and paleoclimate. The PI will test hypotheses regarding use of upland and lowland ecological zones and resource availability relative to environmental conditions and demographic pressures. Anticipated outcomes include a traveling educational exhibit, peer-reviewed journal articles, multiple research assistantships and master’s theses, one dissertation, and two years of training, mentorship, and research experience for a postdoctoral scholar. This award positions a promising researcher for an interdisciplinary STEM career as an engaged teacher and productive Arctic scientist.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目通过将传统知识和同位素分析应用于考古炉灶遗迹的解释，对来自五十多个遗产收藏和实验烹饪特征遗迹的同位素数据进行分析，以重建过去的实验和遗产，从而完善阿拉斯加中部的生存传统的重建。炉灶残留物将与通过在塔纳纳山谷中部不同生态环境的两个地点进行有针对性的挖掘而发现的新挖掘的炉灶进行比较。研究将与指导和实践学习机会相结合。夏季文化营的本科生和研究生以及一名博士后研究员将受益于现场和实验室培训和教育机会。该项目采用 1) 对遗产和实验炉床遗骸进行同位素和分子分析； 2) 在阿拉斯加中部的两个地点（Swan Point 和 Niidhaayh Na'）进行有针对性的挖掘；3) 对新发现的考古材料进行分析；4) 与社区利益相关者一起解释和综合结果。该项目期间收集的宏观植物学和人工数据将用于重建更新世晚期和全新世早期的生存、饮食广度和古气候。项目负责人将测试有关高地和低地生态区的使用以及相对于环境条件和人口压力的资源可用性的假设。预期成果包括巡回教育展览、同行评审的期刊文章、多项研究助理和硕士学位论文、一篇论文以及两年的培训、指导和研究经验。该奖项将跨学科 STEM 职业的有前途的研究人员定位为一名敬业的教师和富有成效的北极科学家。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
