项目摘要

This project consists of excavation of a residential structure associated with a burial/cremation pit feature, well-dated to 10,000 RCYBP (~11,500 calendar years ago) found by our team last summer at Upward Sun River (Xaasaa Na?) (49XBD-298), a multi-component site in the Tanana Basin, central Alaska. The feature is in buried contexts, over 1 meter below surface, in deposits relatively undisturbed by cryoturbation. After consultation with federal, state, and Native officials (stipulated in the Section 106 MOA), all parties agreed to excavation of the feature. Four additional features (to the burial/cremation pit) have been observed to date, and all appear to be outdoor unlined firepits. This proposed excavation is designed to excavate the residential structure, and collect additional geoarchaeological samples to increase our knowledge of site formation, post-depositional disturbance, technology, and subsistence, as well as to specifically evaluate the child cremation to the rest of the structure. At present, no burials have been found in Late Pleistocene/Early Holocene contexts in Eastern Beringia, so our knowledge of an entire suite of mortuary-related behaviors is essentially unknown. This excavation has the potential to contribute transformative data to our understanding of this time period in the Western Hemisphere.

该项目包括挖掘与埋葬/火葬坑特征相关的住宅结构，该结构的年代可追溯到 10,000 RCYBP（约 11,500 历年前），由我们的团队去年夏天在向上太阳河 (Xaasaa Na?) (49XBD-298)（阿拉斯加中部塔纳纳盆地的一个多组成部分遗址）发现。该特征位于地表以下超过 1 米的埋藏环境中，位于相对不受低温扰动干扰的沉积物中。在与联邦、州和原住民官员协商后（MOA 第 106 条规定），各方同意挖掘该地物。迄今为止，已观察到四个附加特征（埋葬/火葬坑），并且所有似乎都是室外无衬里的火坑。此次拟议的挖掘旨在挖掘住宅结构，并收集额外的地质考古样本，以增加我们对场地形成、沉积后扰动、技术和生计的了解，并专门评估儿童火葬对结构其余部分的影响。目前，在白令海峡东部的更新世晚期/全新世早期尚未发现任何墓葬，因此我们对整套与太平间相关的行为的了解基本上是未知的。这次发掘有可能为我们了解西半球这一时期提供变革性数据。
