Rock Island Complex Data: Groundstone from Screened Contexts

The Rock Island Complex Data tables provide a summary of the artifacts recovered during Arizona State University (ASU), Office of Cultural Resource Management's (OCRM) Roosevelt Platform Mound Study (RPMS) excavations at sites in the Rock Island Complex, primarily Bass Point Mound (AZ U:8:23(ASM), AR-03-12-06-177(USFS)) and AZ U:8:400(ASM)(AR-03-12-06-863(USFS)). The Rock Island Complex table Groundstone from Screened Contexts presents a summary of the groundstone artifacts recovered from excavated, screened contexts at Bass Point Mound and AZ U:8:400(ASM).

The table identifies each archaeological site by its Arizona State Museum (ASM) site number and its USFS Tonto Forest number (ASM number/last three digits of Tonto Forest number) (e.g., U:8:23/177). It lists designated archaeological contexts - strata - at the site, and then provides the frequency (count) of different groundstone artifacts for each stratum. 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. 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 data tables "Rock Island Complex Data, Bass Point Mound: Strata" and "Rock Island Complex Data, AZ U:8:400(ASM): Strata" for further data about each stratum, including the assigned stratum type, at the following tDAR urls: https://core.tdar.org/dataset/394255 and https://core.tdar.org/dataset/394256

The Rock Island Complex Data tables were originally published in the Roosevelt Platform Mound Monograph Series No. 4 titled "Where the Rivers Converge, Roosevelt Platform Mound Study: Report on the Rock Island 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/380998
