Schoolhouse Point Mesa Data: Groundstone 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 Groundstone from All Contexts presents a summary of the groundstone 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 groundstone artifacts for each stratum.

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开展的罗斯福台地丘研究（Roosevelt Platform Mound Study，简称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，校舍管理组涵盖品托溪冲沟（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，其相关内容已单独成册报告，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卷册与数据覆盖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。

《校舍角台地数据表：全发掘层位磨制石器》汇总了校舍角台地所有遗址（除单独报告的校舍丘遗址外）经调查与发掘的所有层位（包括过筛与未过筛遗存）中出土的磨制石器（groundstone artifacts）相关信息。该数据表首先列出以亚利桑那州立博物馆（Arizona State Museum，简称ASM）遗址编号命名的考古遗址（所有ASM编号均统一前缀“AZ”，本表省略该前缀，例如U:8:205即对应ASM编号AZ U:8:205），随后列出各遗址对应的考古发掘层位（即地层strata）。这些地层代表了主要的自然或文化沉积事件，例如侵蚀堆积、屋顶塌落堆积、居住面堆积以及无菌底土层。在哈里斯矩阵（Harris Matrix，考古地层学常用分析工具）中，地层以横向排列的相互连接方框进行可视化呈现。在本数据表中，考古发掘层位（地层）的编号由三部分组合而成：ASM遗址编号、冒号、遗迹编号以及地层字母标识（示例：U:3:198:006A、U:3:198:006B）。在单个遗迹内部，各地层通过遗迹编号（例如10、11、12等）与代表特定地层的字母（例如A、B、C）进行标识，字母按降序排列。混杂层位与出土时脱离原生层位的石器标本均以“？”标识。各遗迹（或混杂层位）出土的石器标本均按地层进行计数统计。详细信息请参阅数据表列元数据。如需了解各地层的详细信息（包括地层类型），请通过以下tDAR（数字考古记录库，The Digital Archaeological Record）链接访问校舍角台地地层数据表：

该数据表同时列出了各地层出土的各类磨制石器的出现频次（数量）。

校舍角台地数据表最初收录于《罗斯福台地丘专著系列》第8卷，该卷标题为《校舍角台地考古研究：罗斯福台地丘研究——品托溪复合体校舍管理组校舍角台地遗址报告》。数据表以附录形式刊印于该卷末尾。完整报告卷册详见以下tDAR链接：https://core.tdar.org/document/394293
