Cultural Resources Mitigation at 32MO0296, 32MO0306, 32MO1374, and 32MO1375, Morton County, North Dakota

In the fall of 2005, GLARC conducted archaeological data recovery operations at sites 32MO296, 32MO306, 32MO1374, and 32MO1375 located in Morton county, North Dakota. The sites defi ne short term prehistoric Native American resource extraction sites and campsites that date to the Early to Middle Plains Archaic, Late Plains Archaic, Early Plains Woodland, Middle Plains Woodland, and Late Plains Woodland periods. Previous investigations at 32MO296, 32MO306, 32MO1374, and 32MO1375 determined that the sites met criteria for listing on the National Register of Historic Places. The United States Department of Agriculture, Natural Resources Conservation Service (USDA NRCS) concurred with this recommendation. The archaeological data recovery operations involved a program of systematic surface collection, noninvasive remote sensing, and hand excavation. Well over ten thousand artifacts were recovered from the four sites, and numerous cultural features, defi ning intra-site activity areas, were identifi ed at the sites. Each of the sites produced meaningful data that was
used to address culture history and chronology, lithic and ceramic styles, subsistence and se lement pa erns, regional interaction, and paleoenvironmental conditions relative to the prehistory of the lower Otter Creek valley. Archaeological data recovery was implemented at sites 32MO296, 32MO306, 32MO1374, and 32MO1375 in order to mitigate the eff ects on the cultural deposits from the construction, and inundation, from the proposed combined purpose dam in the Square Bu e Watershed, Square Butte Watershed Dam Site Number 6.

2005年秋季，GLARC在北达科他州莫顿县的32MO296、32MO306、32MO1374及32MO1375四处遗址开展了考古数据抢救性发掘工作。上述遗址均为史前时期北美原住民的短期资源开采营地，年代涵盖平原古风期早中期、平原古风期晚期、平原伍德兰期早期、平原伍德兰期中期以及平原伍德兰期晚期。此前对32MO296、32MO306、32MO1374及32MO1375四处遗址的调查已证实，其符合《国家史迹名录》（National Register of Historic Places）的入选标准。美国农业部自然资源保护局（United States Department of Agriculture, Natural Resources Conservation Service, USDA NRCS）认可了这一评定建议。本次考古数据抢救性发掘工作包含系统性地表采集、非侵入式遥感探测以及手工发掘三项内容。从四处遗址中共出土逾万件遗物，并识别出多处文化遗迹，明确了遗址内部的活动区域划分。四处遗址均产出了具有学术价值的数据，可用于阐释奥特河下游河谷史前时期的文化历史与年代序列、石器与陶器风格、生计与定居模式、区域互动以及古环境状况。为减轻斯夸特布特流域6号综合水利大坝的建设及蓄水淹没对文化遗存造成的破坏，本次考古数据抢救性发掘工作针对32MO296、32MO306、32MO1374及32MO1375四处遗址开展。
