Schoolhouse Point Mesa Data: Decorated Ceramics 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 table Decorated Ceramics from Screened Contexts presents a summary of decorated ceramic vessels recovered from excavated, screened contexts at Schoolhouse Point Mesa (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/394458
https://core.tdar.org/dataset/394376

The table then provides the frequency (count) of individual vessels assigned to different decorated ceramic types for each stratum. Note that the table presents a count of individual vessels (i.e., groups of sherds or single sherds assigned to individual vessels) identified to decorated ceramic type. More specifically, it presents a count of rim sherds that were assigned to a single vessel (The Stage 2 Ceramic Decorated/Intrusive analysis examined rim sherds to determine ceramic type for individually designated vessels).

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体系。亚利桑那州立大学文化资源管理办公室下属的罗斯福台地研究项目（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群组：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。校舍点土丘（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考古遗址。该土丘的相关研究单独成册，其数据亦单独发布（详见https://core.tdar.org/project/394037）。校舍角台地的报告文集与配套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，另外4处坐落于台地西侧俯瞰盐河的阶地地带。

《校舍角台地筛洗遗存纹饰陶器》数据集汇总了校舍角台地（不含单独报告的校舍点土丘）经考古发掘、筛洗后出土的纹饰陶容器遗存。

本数据表首先列出以亚利桑那州立博物馆（ASM）遗址编号命名的考古遗址（所有ASM编号均省略前缀“AZ”，例如U:8:205即对应ASM编号AZ U:8:205），随后将列出各遗址对应的考古埋藏单元（地层）。地层代表了主要的自然或文化沉积事件，例如侵蚀堆积、屋顶坍塌堆积、居住面遗存以及无菌底土层。在哈里斯矩阵（Harris Matrix）中，地层以相互连接的横向方框阵列呈现。本表格中，考古埋藏单元（地层）的标识采用多编号组合格式：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，各地层以遗迹编号（如10、11、12等）加代表特定地层的字母（如A、B、C）进行标识，字母按降序排列。混杂堆积层与无原生埋藏位置的出土器物以“？”标识。各遗迹（或混杂埋藏单元）的出土器物将按地层进行统计汇总。详见数据集列元数据以获取更多细节。如需了解各地层的详细信息（包括地层类型赋值），可访问以下tDAR平台数据集链接：

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

本数据表随后将统计各地层中归入不同纹饰陶类别的单件陶容器的出土频次（数量）。请注意，本表格统计的是经纹饰陶类型鉴定的单件陶容器数量（即归入单件容器的陶片组或单片陶片）。更具体而言，该统计以可归入单件容器的口沿陶片为统计对象（第二阶段纹饰陶/侵入遗存分析通过口沿陶片鉴定单件容器的陶系类型）。
