The field work in this inventory consisted of a pedestrian-type, close interval survey which located and recorded 133 archeological sites. These sites included 111 prehistoric components and 34 historic components. In addition, 103 isolated finds were recorded. During the analysis phase of the project, the cultural resources were separated according to the two major periods of human occupation: prehistoric and historic. The prehistoric sites were investigated in terms of settlement variability from both functional and evolutionary perspectives. The historic sites were examined in light of demographic, settlement, and land-use questions. Judging by the presence of time-diagnostics the prehistoric occupation of the project area extended from the Archaic Period through the Plains Apache of the eighteenth century. The research orientation was to conduct piece-plotting of artifacts at each archeological site for purposes of studying intrasite and intersite variability. The data were organized as 59 quantified observations suitable for computer and statistical manipulation. Two site types were defined: base camps and special activity areas. Most of the historic sites were farmsteads of ranch-related features which dated from the late nineteenth and early twentieth centuries.
