MACROFLORAL ANALYSIS OF SAMPLES FROM SITES IN THE MID-AMERICA PIPELINE COMPANY'S ROCKY MOUNTAIN EXPANSION LOOP PROJECT, EASTERN UTAH AND WESTERN COLORADO

Samples from 21 sites excavated as part of the Mid-America Pipeline Company's Rocky Mountain Expansion Loop pipeline project in eastern Utah and western Colorado were examined for macrofloral remains. These sites represent a wide range of site types and occupations, including the Archaic Era, Formative Era, Anasazi Pueblo II, Protohistoric, Ute, and Historic periods. Macrofloral analysis will be used to determine plant resources utilized by the various occupants of these sites, which will aid in providing information about prehistoric use and adaptations in the project area. Macrofloral analysis can be used to help address problem domains of subsistence, seasonality, paleoenvironment, and site function.本次研究针对犹他州东部与科罗拉多州西部范围内，中美洲管道公司（Mid-America Pipeline Company）落基山扩张环路管道项目所发掘的21处遗址的出土样本，开展了大植物遗存（macrofloral remains）检测分析。这些遗址涵盖多样的遗址类型与人类居留时段，包括古风期（Archaic Era）、形成期（Formative Era）、阿纳萨齐普韦布洛II期（Anasazi Pueblo II）、原历史时期（Protohistoric）、犹特族时期（Ute）及历史时期。大植物遗存分析将用于明确各遗址居留群体所利用的植物资源，可为该项目区域内的史前人类活动与适应策略研究提供关键信息支撑。此外，该分析方法还可用于探讨生计模式、季节节律、古环境（paleoenvironment）及遗址功能（site function）等核心研究领域的科学问题。
