Schoolhouse Point Mesa Data: Lithic Artifacts from All Contexts

The Schoolhouse Point Mesa archaeological sites are part of an extensive settlement system on the southern banks of the Salt River. The Arizona State University, Office of Cultural Resource Management, Roosevelt Platform Mound Study (RPMS) divided the Schoolhouse Point Mesa settlement complex into two groups: the Schoolhouse Management Group and the Livingston Management Group. The Schoolhouse Management Group includes those sites on the west side of Pinto Creek Wash, while the Livingston Management Group includes sites on the east side of the wash. Schoolhouse Point Mound (AZ U:8:24(ASM), AR-03-12-06-13a(USFS)) is the largest site in the Schoolhouse Management Group and on the mesa. The mound is treated in a separate report volume and its data are reported separately (Please see https://core.tdar.org/project/394037). The Schoolhouse Point Mesa report volumes and data document the remaining 23 archaeological sites in the Schoolhouse Management Group. Nineteen of the sites are located on the mesa, while four are west of the mesa on the terraces overlooking the Salt River.

The Schoolhouse Point Mesa Data table Lithics from All Contexts presents a summary of the lithic artifacts recovered from all investigated contexts (both screened and unscreened) at Schoolhouse Point Mesa sites (except Schoolhouse Point Mound, which is reported separately). The table lists archaeological sites designated by Arizona State Museum (ASM) site numbers (without the "AZ" common to all ASM numbers) (e.g., U:8:205 = ASM site number AZ U:8:205). It then lists designated archaeological contexts - strata - at each site. The strata represent major natural or cultural depositional events such as erosional fill, roof fall, floor contexts, and sterile substrate. Strata are depicted as horizontal rows of interconnected boxes on a Harris Matrix. In this table, the archaeological contexts - strata - are identified by a combination of numbering systems: the ASM site number, a colon, the feature number, and the stratum letter designation (EX: U:3:198:006A, U:3:198:006B). Within a feature, each stratum is designated by the feature number (e.g., 10, 11, 12, etc.) and a letter that designates a particular stratum (e.g., A, B, C). The letters are assigned in descending order. Mixed levels and artifacts collected out of context are designated by a "?". Artifacts from each feature (or mixed context) are tallied according to strata. Please see column metadata for further detail. Please also see the Schoolhouse Point Mesa strata data tables for further data about each stratum, including the assigned stratum type, at the following tDAR urls:

https://core.tdar.org/dataset/394457
https://core.tdar.org/dataset/394458
https://core.tdar.org/dataset/394376

The table then provides the frequency (count) of different lithic artifact types for each stratum. Note that the table table provides a count of individual artifacts, and not individual pieces of lithic material.

The Schoolhouse Point Mesa Data tables were originally published in the Roosevelt Platform Mound Monograph Series No. 8 titled "The Archaeology of Schoolhouse Point Mesa, Roosevelt Platform Mound Study: Report on the Schoolhouse Point Mesa Sites, Schoolhouse Management Group, Pinto Creek Complex." The tables were published in an appendix at the end of the volume. Please see the report volume at the following tDAR URL: https://core.tdar.org/document/394293

校舍点台地考古遗址（archaeological sites）隶属于盐河南岸一处规模宏大的聚落系统（settlement system）。亚利桑那州立大学文化资源管理办公室（Office of Cultural Resource Management）开展的罗斯福台地丘研究项目（Roosevelt Platform Mound Study, RPMS）将校舍点台地聚落群划分为两个管理组：校舍管理组与利文斯顿管理组。校舍管理组涵盖平托溪冲沟（Pinto Creek Wash）西侧的全部遗址，利文斯顿管理组则包含该冲沟东侧的遗址。校舍点丘（Schoolhouse Point Mound，编号为AZ U:8:24(ASM)、AR-03-12-06-13a(USFS)）是校舍管理组乃至整个台地上规模最大的遗址。该丘体的相关研究已单独成册，数据亦单独发布（详见https://core.tdar.org/project/394037）。本数据集对应的报告及数据覆盖了校舍管理组内其余23处考古遗址，其中19处遗址位于台地之上，剩余4处分布于台地西侧俯瞰盐河的阶地上。

《校舍点台地全发掘单位石制品（lithic artifacts）》数据表汇总了校舍点台地所有遗址（不含单独发布的校舍点丘）在全部发掘单位（含筛洗（screened）与未筛洗（unscreened）遗存）中出土的石制品。本表以亚利桑那州立博物馆（Arizona State Museum, ASM）的遗址编号（省略所有ASM编号共有的前缀“AZ”，例如U:8:205对应ASM编号AZ U:8:205）标注各遗址，随后依次列出各遗址的发掘单位——即地层（strata）。地层代表了主要的自然或文化堆积事件，包括侵蚀充填、塌顶堆积、居住面遗存以及无人工遗物的基质（sterile substrate）。在哈里斯矩阵（Harris Matrix）中，地层以横向排列的互连方框进行可视化呈现。本表中，发掘单位（地层）通过编号组合进行标识：ASM遗址编号 + 冒号 + 遗迹编号（feature number） + 地层字母代号（示例：U:3:198:006A、U:3:198:006B）。在单个遗迹内部，各地层以遗迹编号（如10、11、12等）加字母代号（如A、B、C）进行标识，字母按从上至下的堆积顺序编号。混合堆积层与出土层位不明的遗存以“？”标注。各遗迹（或混合发掘单位）的出土遗存均按地层进行统计计数。更多细节请参阅本表的列元数据（metadata）。若需获取各地层的详细信息（包括已指定的地层类型），请访问以下tDAR平台的校舍点台地层表数据集链接：

本表提供了各地层中各类石制品的出土频次（数量）。请注意：本表统计的是单件石制品的数量，而非石质原料的块数。

校舍点台地数据集最初收录于《罗斯福台地丘专著系列（monograph series）》第8卷，题为《校舍点台地考古研究：罗斯福台地丘研究项目——平托溪复合体校舍管理组校舍点台地遗址报告》。本表以附录形式刊载于该卷末尾。完整报告卷册可通过以下tDAR平台链接查阅：https://core.tdar.org/document/394293
