and surface visibility were essentially the same throughout all of Fields 2, 3, and 4;
therefore, the spatial constriction of artifact deposition cannot be attributed to a bias due
to variations in visibility. The consistency and uniformity of deposition is a major feature
derived from the analysis. The PDZ spans three separate fields, each under differing use
patterns and methods of cultivation and cattle grazing, which further suggest the limited
concentration of artifacts was a result of ancient activity and deposition as opposed to
contemporary impacts to the surface.
There are a number of factors that warrant further consideration of the PDZ. First
is the density of material, 124 sherds per 50 m x 50 unit within the PDZ compared to 21
sherds in the remainder of the surveyed area units. Second, within a 50 m-wide perimeter
zone (55,000 m²) that encircles the 300 m x 150 m PDZ (45,000 m²) only 28 ceramic
pieces were recovered (see Figure 6.8). The rate and suddenness of the depositional drop-
