Schoolhouse Point Mesa Data: Lithic Artifacts from Screened 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 Screened Contexts presents a summary of the lithic artifacts recovered from excavated, screened contexts 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

校舍角台地（Schoolhouse Point Mesa）考古遗址群隶属于盐河（Salt River）南岸一处规模宏大的定居点系统。亚利桑那州立大学文化资源管理办公室（Arizona State University, Office of Cultural Resource Management）下属的罗斯福台地丘研究项目（Roosevelt Platform Mound Study, RPMS）将校舍角台地定居点复合体划分为两个管理组：校舍管理组与利文斯顿管理组。其中，校舍管理组涵盖平托溪冲沟（Pinto Creek Wash）西侧的所有遗址，利文斯顿管理组则包含该冲沟东侧的遗址。校舍丘遗址（Schoolhouse Point Mound，编号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，其相关研究已单独成册，数据亦单独发布（详见https://core.tdar.org/project/394037）。本次校舍角台地的报告集与数据集记录了校舍管理组剩余的23处考古遗址：其中19处位于台地之上，另有4处分布在台地西侧俯瞰盐河的阶地上。

《校舍角台地数据集：筛洗堆积中的石制品》数据表汇总了校舍角台地各遗址（校舍丘遗址除外，其数据已单独发表）经发掘、筛洗后出土的石制品（lithic artifacts）遗存。该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编号共通前缀“AZ”）标注各考古遗址，例如U:8:205即对应ASM编号AZ U:8:205的遗址。随后列出各遗址的考古堆积单元——地层（stratum，复数strata），这些地层代表了主要的自然或文化堆积事件，例如侵蚀堆积、屋顶塌落堆积、居住面堆积以及无文化层母质。在哈里斯矩阵（Harris Matrix）中，地层以横向排列的互连方框表示。本表中，考古堆积单元（地层）通过组合编号系统标识：ASM遗址编号+冒号+遗迹（feature）编号+地层字母标识，例如U:3:198:006A、U:3:198:006B。在单个遗迹内部，各地层通过遗迹编号（如10、11、12等）与代表特定地层的字母（如A、B、C）共同标识，字母按倒序分配。混杂堆积层与出露层位不明的出土遗物以“？”标注。各遗迹（或混杂堆积单元）出土的遗物将按地层进行计数统计，详细说明请参见列元数据。如需获取各地层的详细数据（包括地层类型），可通过以下tDAR链接查阅校舍角台地地层数据表：

本表提供了各地层中不同石制品类型的出现频次（计数）。请注意，本表统计的是单个出土遗物的数量，而非石质原料的个体块数。

校舍角台地数据集最初发表于《罗斯福台地丘专著系列》第8号，题为《校舍角台地考古研究：罗斯福台地丘项目——平托溪复合体校舍管理组遗址报告》，该数据表作为附录收录于该专著末尾。完整报告集详见以下tDAR链接：https://core.tdar.org/document/394293
