ABSTRACT The Ironwood Quarry is one of a series of milling implement quarries in the Palo Verde Mountains Quarry District of southern California. This quarry presents a unique circumstance where most manufacturing locations are segregated and can be individually identified. The low-density of the general debris of quarrying and preliminary shaping of preforms for milling implements thus facilitates understanding of individual manufacturing episodes. Data collected from the quarry allowed preliminary analyses of frequencies and distributions of milling implement manufacturing activities associated with pestle, milling platform (metate), and perhaps handstone (mano) production. Manufacturing failures left at the quarry demonstrate that it was much more difficult to produce a stone pestle than a metate. The labor investment in making common household tools suggests that a high value was placed on these tools by local cultural groups. These data have implications for other milling implement quarry landscapes where a high density of debris from multiple episodes of manufacture over time is more difficult to understand.

加利福尼亚州河滨县 Ironwood 采石场的铣削工具制造

摘要 Ironwood 采石场是南加州帕洛佛得山采石场的一系列铣削工具采石场之一。这个采石场呈现出一种独特的情况，大多数制造地点都是隔离的，可以单独识别。因此，采石和铣削工具预成型件的一般碎屑的低密度有助于理解各个制造过程。从采石场收集的数据允许对与杵、铣削平台（金属）和可能的手石（马诺）生产相关的铣削工具制造活动的频率和分布进行初步分析。采石场留下的制造故障表明，生产石杵比生产金属研杵要困难得多。制造普通家用工具的劳动力投资表明当地文化群体对这些工具的重视程度很高。这些数据对其他铣削工具采石场景观有影响，在这些地区，随着时间的推移，多次制造过程中产生的高密度碎片更难以理解。
