RADIOCARBON DATING FOR PROJECT 2-07-359, WASATCH MOUNTAINS, UTAH

Bulk soil samples from nine locations in two trenches were floated to recover both macroscopic and microscopic charcoal fragments suitable for radiocarbon analysis. These samples were recovered from alluvial fan and debris-flow deposits located along the base of the west side of the Wasatch Mountain Range in Salt Lake City, Utah. These deposits are believed to date from 5000-14,000 radiocarbon years before present. Microscopic charcoal from three samples were submitted for AMS radiocarbon analysis.从两条探槽的9个采样点采集的大体积土壤样品经浮选处理，以回收适用于放射性碳测年（radiocarbon analysis）的宏观与微观炭屑。这些样品采自美国犹他州盐湖城瓦萨奇山脉（Wasatch Mountain Range）西侧山麓的冲积扇与泥石流沉积体。据推断，该类沉积体的年代介于距今5000至14000放射性碳年之间。从3个样品中提取的微观炭屑被送往开展加速器质谱放射性碳测年（AMS radiocarbon analysis）分析。
