Decisions related to the production of lithic technology involve landscape-scale patterns of resource acquisition and transport that are not observable in assemblages from any one single site. In this study, we describe the stone artifacts from a discrete cluster of stone artifacts assigned to the Robberg technocomplex (22-16 ka) at the open-air locality of Uitspankraal 9 (UPK9), which is located near two major sources of toolstone in the Doring River catchment of Western Cape, South Africa. OSL dating of the underlying sediment unit provides a terminus post quem age of 27.5 ± 2.1 ka for the assemblage. Comparison of near-source artifact reduction at UPK9 with data from three rock shelter assemblages within the Doring watershed – Putslaagte 8 (PL8), Klipfonteinrand Rock Shelter (KFR), and Mertenhof Rock Shelter (MRS) – suggests that “gearing-up” with cores and blanks occurred along the river in anticipation of transport into the wider catchment area. The results reveal an integrated system of technological supply in which raw materials from different sources were acquired, reduced, and transported in different ways throughout the Doring River region.

与石器技术生产有关的决策涉及资源获取和运输的横向模式，这些模式在任何一个站点的组合中都无法观察到。在这项研究中，我们描述了位于Uitspankraal 9（UPK 9）的露天地点（位于两个主要的工具岩源附近）的离散的石器物集群中的石器物，这些石器物分配给了Robberg技术复合体（22-16 ka）在南非西开普的多林河流域。底层沉积物单元的OSL测年为该组合提供了27.5±2.1 ka的终末期。UPK的近源伪像减少的比较图9中的数据来自多林河流域内的三个岩石避难所集合– Putslaagte 8（PL 8），Klipfonteinrand岩石避难所（KFR）和Mertenhof岩石避难所（MRS）–提示沿河发生了“积聚”，包括岩心和毛坯预期将运输到更广泛的集水区。结果揭示了一个完整的技术供应系统，在该系统中，来自不同来源的原材料以不同的方式获得，减少和运输了整个多灵河地区。
