The AOI was determined by a review of the 2001 Aster image of the alluvial fan, which was also used during the previous campaigns of the current project. Furthermore, the methods employed during this season compliment those of previous campaigns; site perimeters (sometimes with internal structures, craft activity areas, kilns etc. also identified) were recorded with a GPS unit, and detailed descriptions of the sites were always recorded in field notes. The survey was based on a grid consisting of 20 x 20 m. squares, occasionally sub-divided in squares of 5 x 5 m. when concentrations of pottery fragments indicated more complex archaeological deposits.
Survey was conducted by a team of ten people spaced along a line of 40 m. (two 20 x 20 m. squares), flanked at each end by a team member equipped with a GPS to contain the line, and one team member with a compass following several paces behind to help guide and keep the spacing between the surveyors. When pottery was encountered, a complete count of the sherds within that 20 x 20 m. square was made, along with any other anthropogenic material. The pottery counts were made on the basis of different size classes: “mini” for fragments less than 1 cm in diameter, “small” for sherds less than 2-3 cm. in their largest dimension, “medium” for sherds less than 7-8 2
