With only a few exceptions, the method of excavation used during the l99l and 1992 seasons at the Clampitt site consisted of the removal of plow zone deposits in regular levels that measured between 10 and 20 cm in thickness. In the first four excavation units begun in 1991, the plow zone deposits were sampled by passing all soil through one quarter inch mesh. The plow zone fill in subsequent units was not screened, and only diagnostic artifacts discovered during shovelling were recovered ( Plate 1 ). Once the plow zone was removed, the underlying subsoil was examined for the presence of cultural features. All features were excavated with trowels in 10 to 20 cm thick levels and mapped and photographed in plan and profile. All feature fill was passed through one quarter inch mesh, and 10 liter flotation samples were collected. Following these methods, a total of 782 square meters of the site was exposed over the two seasons of excavation.
Excavation units consisted of either three meter by three meter squares or one to two meter wide test trenches. In a few instances, excavation units of more irregular dimensions were utilized, usually as extensions of formal units. All square units were labeled alphabetically (i.e. beginning with "A") as they were laid out. Early in the 1992 season, the twenty-sixth unit was established (Unit "Z") which required the use of double letters for subsequent squares (e.g."AA", "BB", etc.). A total of 46 complete squares were excavated plus several small extension units of irregular sizes (Figure 11).
Test trenches were numbered consecutively beginning with " 1" and ending with "32", and no unit or trench designations were repeated during the two seasons of excavation (Figure 12). In the same way, no feature number designations were used twice (Figures 13a, 13b, 13c, 13d). In contrast, post molds were numbered exclusively within each unit, and, consequently, numbers were repeated in subsequent units. The single burial feature that was discovered was labeled "Burial Feature 1".
