Uplands Complex Data, Unit 11 Sites: Strata

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.
