POLLEN ANALYSIS FOR SAMPLES FROM 5MF6875 AND 5MF7411, VERMILLION BASIN, NORTHWEST COLORADO

During the construction monitor of the Wexpro Company Musser 31, 38, 39, and Carl Allen 37 well pad in the Vermillion Basin of northwestern Colorado, features were discovered that were identified as part of sites 5MF6875 and 5MF7411. Feature 16 yielded a radiocarbon age of 5750 ± 40 BP and has been associated with nearby site 5MF6875. The other four features dated between 860 ± 30 BP and 1690 ± 30 BP. Pollen analysis was undertaken on fill from each of these features in an effort to identify foods that might have been processed.

在美国科罗拉多州西北部弗米利恩盆地的Wexpro公司Musser 31、38、39号井场及Carl Allen 37号井场的施工监测工作中，研究人员发现了若干考古遗迹，经确认这些遗迹分属遗址5MF6875与5MF7411。其中遗迹16的放射性碳年龄（radiocarbon age）为5750 ± 40 BP（Before Present，距今），且被关联至附近的遗址5MF6875。其余四处遗迹的年代测定结果介于860 ± 30 BP至1690 ± 30 BP之间。研究人员对上述所有遗迹的填土开展了孢粉分析，旨在识别其中可能存在的加工食物遗存。
