POLLEN, MACROFLORAL, AND ORGANIC RESIDUE (FTIR) ANALYSIS FROM SITES 42KA7714 AND 42KA7715, KANE COUNTY, UTAH

Sites 42KA7714 and 42KA7715, Kane County, Utah, were documented during monitoring of Highway 89 construction in the Kanab Canyon vicinity (MOAC 13-307 project). An isolated basin-shaped hearth (42KA7714) provided a radiocarbon date of AD 970-1025. This basin yielded charcoal, fire-altered rock, and bone fragments, but no other artifacts (Hanna Romes, personal communication June 23, 2015). Macrofloral and pollen analysis was requested for two samples from Feature A, site 42KA7714.

Located slightly to the north 42KA7715 displayed several features, including a basinshaped pit structure (Feature A), a small basin-shaped depression possibly used as a storage pit (Feature B), and a potential roasting feature (Feature C) (Hanna Romes, personal communication June 23, 2015). All features exhibited disturbance. Feature A, yielded a radiocarbon date of AD 235-385, placing its affiliation with Basketmaker II, but provided no culturally affiliated artifacts. Located southeast of Feature A, Feature B fill was distinguished from the Layer II horizon by charcoal, staining, and large pebbles, with surrounding flakes and one metate recovered north of the feature (Hanna Romes, personal communication June 23, 2015). Feature C, containing black silty sand and charcoal flecking, located north of other site features, was associated with a metate, mano, core, and single ceramic sherd (Hanna Romes, personal communication June 23, 2015). In total, twenty samples, including sediment controls, were submitted from 42KA7715 for pollen, macrofloral, and organic residue (FTIR) analysis. Nine samples submitted from non-feature site contexts complemented the four samples from Feature A, three samples from Feature B, and four samples for Feature C.

美国犹他州凯恩县的42KA7714与42KA7715两处遗址，是在卡纳布峡谷周边的89号公路建设监测工作（MOAC 13-307项目）期间被记录归档的。孤立的盆形火塘（42KA7714）经碳十四测年，年代为公元970年至1025年。该火塘出土了木炭、火烧岩石与骨碎片，但未发现其他人工遗物（Hanna Romes，2015年6月23日私人通信）。研究人员已申请对42KA7714遗址A遗迹的两份样本开展大植物遗存与孢粉分析。
位于42KA7715遗址稍偏北侧的区域，该遗址展现出多处遗迹，包括盆形坑状结构（遗迹A）、可能用作储藏坑的小型盆形凹陷（遗迹B）以及疑似烧烤遗迹的遗迹C（Hanna Romes，2015年6月23日私人通信）。所有遗迹均存在扰动痕迹。遗迹A经碳十四测年为公元235年至385年，其文化归属为篮器时代二期（Basketmaker II），但未出土带有明确文化属性的人工遗物。遗迹B的填土位于遗迹A东南侧，可通过木炭、染色痕迹与大砾石与第二层地层区分开来，遗迹周边散落有碎屑，且在遗迹北侧出土了一件磨石盘（metate）（Hanna Romes，2015年6月23日私人通信）。遗迹C位于遗址其他遗迹的北侧，内部含有黑色粉砂质砂与炭屑斑点，伴生有磨石盘、磨石杵（mano）、石核与一件陶片（Hanna Romes，2015年6月23日私人通信）。42KA7715遗址共提交了包括沉积物对照样本在内的20份样本，用于开展孢粉、大植物遗存与有机残留物傅里叶变换红外光谱（FTIR）分析。其中，来自遗址非遗迹区域的9份样本，与遗迹A的4份样本、遗迹B的3份样本以及遗迹C的4份样本形成补充。
