This records information collected by field teams for each survey given unit. This information includes the number of different artifact classes (pottery, tile, stone, other) counted in each fieldwalker's transects, which provides the total count and density for the unit. It also includes environmental features of the unit (vegetation, soil, etc.) and the logistics of collection (date, time, location, etc.). We recorded the information on paper forms in the field at the time of survey and subsequently keyed the data into a Microsoft Access database, which we linked to a GIS plot of the survey units. We scanned the paper forms and archived a copy of the physical forms at the University of North Dakota.
