<br />H. Site formation and transformation <br />- The deposits in the locus, surrounding the feature, <br />represent discrete activity areas. <br />- The materials at Locus A represent activities of a <br />single component rather than discrete, horizontally <br />distributed components that are unrelated in time. <br />I. Paleoenvironment <br />- The site was occupied during a relatively warm and dry <br />climatic episode. <br />Methods <br />The field and analytic methods are selected to meet the <br />maximum data recovery requirements of the research hypotheses <br />posed within the problem domain parameters. Work at the site <br />will begin with the establishment of a datum and the laying out <br />of a Union grid system based on 1 by 1 meter squares. Grid <br />squares will be referenced from corners closest to the datum. <br />Base maps will be prepared using 2-foot contour maps <br />provided by Lillyland, Inc. Mapping will be conducted using a <br />• transit-level and stadia rod. Surface artifacts within the <br />Locus will be mapped and collected. <br />Excavation units will be superimposed over the suspect <br />feature. At least ten additional units will be dug based on a <br />geometric pattern and spread across the untested areas of the <br />locus in an attempt to located any additional features (Figure <br />3). Hand tools will be used to excavate all units. Excavation <br />will proceed in Scm or lOcm levels, or along stratigraphic <br />levels if they are well defined; sterile levels will be <br />established by excavation of an additional 10 to 20cm. All soil <br />will be screened through 1/8th-inch screen except for hearth <br />contents which will be sifted through 1/16th-inch screen. <br />Artifact tools found in-situ will be referenced to the <br />control corner and bagged separately. Other artifacts and <br />ancillary specimens will be bagged in aggregate, and labeled by <br />level and unit. Flotation, carbon and pollen samples will be <br />collected as warranted. Soils will be assessed by texture and <br />color. Finally, features will be photographed, and plan and <br />profile views will be drawn. <br />In the laboratory, artifacts will be sorted according to a <br />classificatory scheme. Since no perishables are expected, this <br />will amount to the basic chipped and groundstone categories. <br />. For chipped stone, there are projectile points, other bifaces, <br />9 <br />
