3 <br />• somewhat. A fair amount of disturbance, due primarily to vehicular <br /> traffic, was observed. A vehicle track cuts through the area from <br />north to south and the extreme southeast portion of the survey area <br />has been disturbed by construction of a bladed road. Some overgrown <br />bulldozer disturbance associated with a few scattered parts from some <br />type of earth moving vehicle were observed on a low ridge in the <br />east-central portion of the survey area. <br />The survey area is located on the east side of a north-south <br />ridge system overlooking Bolton Draw and the Canadian River to the <br />east. Slope in the survey area runs generally from the northwest <br />down to the southeast. Several low ridges run through the survey <br />area in a general ESE direction. <br />The only evidence of possible prehistoric cultural activity <br />• found in the survey area consists of one flake of light brown chert <br />(Isolated Find 111) found in the northern part of the survey area <br />(cf. Figure 1 for specific location). The flake is 36.4 mm long, <br />30.8mm wide and 7.7mm thick. There are two levels of patination on <br />the flake - a heavily patinated cortical layer at the proximal end <br />and on one side of the flake and more recent patinatinn on the dorsal <br />side of the flake. There appears to be some platform preparation <br />retouch along one edge of the flake. No evidence of use wear could <br />be seen. The flake was found at the end of a low ridge and the <br />immediate area was intensively examined. No other evidence of cultural <br />activity was found, however. <br />The closest known sites to the survey area are SJA302 and SJA287, <br />. located on the east side of Bolton Draw 2.0 and 2.2 kilometers directly <br />
