Rock Island Complex Data: Shell Taxa from All 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 Data table Shell Taxa from All Contexts presents a summary of the shell taxa of the shell artifacts recovered from all contexts (both screened and unscreened) at excavated sites (in this instance, only Bass Point Mound).

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 shell artifacts with different shell taxon designations. Note that it provides a count of artifacts (NOT individual shell pieces) identified to individual taxa. Thus, a shell bracelet in 3 pieces identified to a shell taxon will count as 1 artifact for that taxon.

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 table "Rock Island Complex, Bass Point Mound Data: Strata" for further data about each stratum, including the assigned stratum type, at the following tDAR url: http://core.tdar.org/dataset/394255

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
