POLLEN AND MACROFLORAL ANALYSES OF FOUR SITES AROUND JACKSON LAKE, WYOMING

Eight pollen and seventeen flotation samples were collected from
features at seven archaeological sites along the shores of Jackson Lake,
Wyoming. These sites are located in areas supporting primarily coniferous
timber surrounding Jackson Lake. Lodgepole pine and fir make up most of
this timbered community, while the understory currently exhibits large
pioneer plant communities as a result of the disturbance caused by
fluctuations in the level of Jackson Lake. These sites range in age from
Paleo-Indian to Late Prehistoric. 80th the pollen and macrofloral
(flotation) samples were collected from features in an effort to obtain data
concerning the floral portion of the subsistence base at these sites.

研究团队从怀俄明州杰克逊湖沿岸7处考古遗址的遗迹中，采集了8份花粉样本与17份浮选样本。这些遗址坐落于杰克逊湖周边以针叶林为主的区域，其中扭叶松（Lodgepole pine）与冷杉构成了该林区的主体植被；受杰克逊湖水位波动引发的干扰影响，当前林下植被呈现出大面积的先锋植物群落。这些遗址的年代跨度从古印第安时期（Paleo-Indian）直至史前晚期。本次采集的花粉与大植物遗存（浮选）样本均来自各遗址遗迹，旨在获取有关这些遗址生业基础中植物类组成部分的数据。
