古代(11.5-8.0ka)大盆地的居住者在穿越觅食领土时遇到了无数的石块来源。对这些来源材料制造的工具进行的来源来源和石制技术分析阐明了流动的几个方面，包括材料运输的地理规模以及人口流动的范围和可能的路线。这项研究表明，中部大盆地群穿越了大片勉强维持生存的领土，从北到南绵延400多公里，流动策略可能关键是资源丰富的湿地的分布。来源代表性的变化与变暖和变干的趋势相平行，这表明在大约9.5-8.5ka之后，随着湿地的减少，古生代的觅食范围发生了转移。
Paleoarchaic (11.5–8.0 ka) occupants of the Great Basin encountered numerous lithic sources as they moved across foraging territories. Source provenance and lithic technologic analyses applied to the tools manufactured from these source materials elucidate several aspects of mobility, including the geographic scale of material conveyance and extent and possible routes of population movement. This research indicates that central Great Basin groups traversed large subsistence territories, extending more than 400 km from north to south, with mobility tactics probably keyed to the distribution of resource-rich wetlands. Changes in source representation parallel warming and drying trends, suggesting that Paleoarchaic foraging ranges shifted as wetlands diminished after about 9.5–8.5 ka.
