A single radiocarbon date derived from the Buhl burial in south-central Idaho has frequently been used as a data point for the interpretation of the Western Stemmed Tradition (WST) chronology and technology because of the stemmed biface found in situ with the human remains. AMS dating of bone collagen in 1991 produced an age of 10,675 ± 95 14C BP, immediately postdating the most widely accepted age range for Clovis. The Buhl burial has been cited as evidence that stemmed point technology may have overlapped with Clovis technology in the Intermountain West. We discuss concerns about the radiocarbon date, arguing that even at face value, the calibrated date has minimal overlap with Clovis at the 95.4% range. Furthermore, the C:N ratio of 3.69 in the analyzed collagen is outside of the typical range for well-preserved samples, indicating a postdepositional change in carbon composition, which may make the date erroneously older or younger than the age of the skeleton. Finally, the potential dietary incorporation of small amounts of anadromous fish may indicate that the burial is younger than traditionally accepted. For these reasons, we argue that the Buhl burial cannot be used as evidence of overlap between WST and Clovis.

重新评估爱达荷州中南部 Buhl 墓葬的放射性碳日期及其与西部山区传统 - 克洛维斯辩论的相关性

源自爱达荷州中南部 Buhl 墓葬的单一放射性碳日期经常被用作解释西方茎干传统 (WST) 年代学和技术的数据点，因为在原位发现了人类遗骸的茎干双面。1991 年骨胶原的 AMS 测年产生了 10,675 ± 95 14C BP 的年龄，紧接着 Clovis 最广泛接受的年龄范围。Buhl 墓葬被引用为证据，表明干点技术可能与 Intermountain West 的 Clovis 技术重叠。我们讨论了对放射性碳日期的担忧，认为即使按面值计算，校准日期与 Clovis 的重叠范围也最小，为 95.4%。此外，所分析的胶原蛋白中的 C:N 比为 3.69，超出了保存完好样品的典型范围，表明碳成分的沉积后变化，这可能使日期错误地比骨骼的年龄更老或更年轻。最后，少量溯河鱼类的潜在饮食掺入可能表明墓葬比传统上接受的要年轻。由于这些原因，我们认为不能将布尔墓葬用作 WST 和克洛维斯之间重叠的证据。
