This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project consists of emergency conservation and analysis of several Early Holocene organic tools from the Gerstle River site, in central Alaska. Excavation in 2008 recovered three organic points in well-stratified contexts, with what appear to be slots for microblade insets. These finds are directly associated with Component 3 at the site, dating to ~10,100 cal BP. The points are worked: some exhibit hafting elements and may also contain embedded lithics (some silt has yet to be removed). The organic artifacts are have been recovered from intermittently frozen soils and are drying out, necessitating immediate stabilization efforts as well as long-term conservation. The remains are currently stable, provided they do not undergo handling, which limits analyses that can be performed. Once conserved, they will undergo X-ray analysis to help describe the morphology and to identify any small lithics that might remain embedded in the slots. Residue-analysis, lithic analysis, and technological (manufacturing techniques) analyses will be performed once the artifacts are conserved.

该奖项是根据2009年美国恢复和再投资法案（公法111-5）资助的。该项目包括紧急保护和分析几个早期全新世有机工具，从格斯特尔河网站，在阿拉斯加中部。2008年的挖掘在分层良好的环境中发现了三个有机点，似乎是微型刀片插入的插槽。这些发现与该遗址的第3组分直接相关，可追溯到约10，100 cal BP。这些点是经过加工的：有些显示出轴元素，也可能包含嵌入式岩性（一些淤泥尚未被清除）。这些有机文物是从间歇性冻土中回收的，正在干涸，需要立即进行稳定工作和长期保护。这些遗骸目前情况稳定，前提是不进行处理，这限制了可以进行的分析。一旦保存下来，它们将接受X射线分析，以帮助描述形态，并确定任何可能仍然嵌入槽中的小岩屑。一旦文物被保存，将进行残留物分析，岩性分析和技术（制造技术）分析。
