BARGER GULCH LOCALITY B This database includes all field and laboratory data from the Barger Gulch Archaeological Project. It includes all field data from the excavation of Barger Gulch Locality B (5GA915), a Folsom site in Grand County, Colorado It also includes mapping of surface artifacts and auger data. Laboratory analysis data for all lithic artifacts recovered from excavations are also included as are radiocarbon dates from excavations. These data will be published as a companion dataset to the book Barger Gulch: A Folsom Campsite in the Rocky Mountains (University of Arizona Press) by Todd Surovell. These data are available as both a Microsoft Access relational database and also with the same database broken down into flat csv files, each of which is a table from that database.

Within Barger Gulch Coding Sheets, the field Catalog Number is critical. The following tables link to Barger Gulch Coding Sheets through the variable Catalog Number: Bifaces, Burned Bone, Channel Flakes, Cores, Debitage, Ground Stone, Points and Preforms, Radiocarbon Dates, Refits, Refitted Items Attributes, Screen Bags, and Tools. Two other important linkages exist. The table Excavation Units links to Barger Gulch Coding Sheets through the fields Block and Unit. The table Barger Gulch Quad Classfication links to Barger Gulch Coding Sheets through the fields Block, Unit, and Quad. The following are standalone tables: Augers, Barger Gulch Surface Collection, Excavation Polygons, Feature Polygons, and Topo Shots. TWO ADDITIONAL FILES ARE INCLUDED AS REFERENCES FOR THE DATASET: 1. Excavation manual.pdf – This manual was given to excavators beginning in the 2005 field season as guide for filling out paperwork. This document is especially relevant to the table “Barger gulch Coding Sheets,” which includes all data collected by excavators during all excavations. 2. Lithic Analysis Methods.pdf. This is a useful guide to the lithic analysis data include herein. It is take directly from Surovell, Todd A. (2003) The Behavioral Ecology of Folsom Lithic Technology.
