Schoolhouse Point Mesa Data: Lithic Size Class Data 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 Lithic Size Class from All Contexts presents a summary of the size grades 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 lithic artifacts within different size grades (bins). All lithic artifacts (from screened contexts) - irrespective of artifact type and material type - were assigned to a size class.

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

斯科霍斯角台地（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）将斯科霍斯角台地定居点复合体划分为两个管理群组：斯科霍斯管理群组与利文斯顿管理群组。其中，斯科霍斯管理群组涵盖品托溪冲沟（Pinto Creek Wash）西侧的全部遗址，利文斯顿管理群组则包含该冲沟东侧的遗址。斯科霍斯点丘（Schoolhouse Point Mound，编号为AZ U:8:24(ASM)、AR-03-12-06-13a(USFS)）是斯科霍斯管理群组乃至整个台地上规模最大的遗址，其相关研究单独成册，数据亦单独发布（详见https://core.tdar.org/project/394037）。本数据集依托的斯科霍斯角台地报告与数据，记录了斯科霍斯管理群组剩余的23处考古遗址：其中19处位于台地之上，另外4处则分布于台地西侧俯瞰盐河的阶地地带。

《所有发掘背景下的石制品尺寸等级》（Schoolhouse Point Mesa Data table Lithic Size Class from All Contexts）数据表汇总了斯科霍斯角台地所有发掘背景（包括过筛与未过筛地层）中出土的石制品尺寸分级数据（不含单独成册报告的斯科霍斯点丘遗址）。该数据表以亚利桑那州立博物馆（Arizona State Museum, 简称ASM）的遗址编号（省略所有ASM编号共有的前缀“AZ”，例如U:8:205即对应ASM编号AZ U:8:205）标注各考古遗址，随后依次列出各遗址的指定考古发掘背景——即地层（strata，单数stratum）。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、屋顶坍塌、居住面堆积以及无菌底土层。在哈里斯矩阵（Harris Matrix，地层学分析常用图示方法）中，地层以横向排列的互连方框来表示。本数据表中，考古发掘背景（地层）通过编号组合标识：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，每个地层以遗迹编号（如10、11、12等）与代表特定地层的字母（如A、B、C）标识，字母按倒序分配。混合堆积层与无明确出土地点的出土遗物以“？”标注。各遗迹（或混合发掘背景）出土的遗物均按地层进行统计。详细信息请参阅数据表列元数据。如需了解各地层的详细数据（包括已指定的地层类型），可访问以下tDAR数据库链接查看斯科霍斯角台地地层数据表：

本数据表随后列出了不同尺寸分级（组距）下的石制品出现频次（计数）。所有来自过筛发掘背景的石制品，无论器类与材质，均被归入相应的尺寸类别。
