FIELD METHODS <br />Field work was conducted according to the design out- <br />lined in the testing proposal (Lennon and Wheeler 1980). <br />The intensity of the program varied with site size and nature. <br />The testing program commenced by flagging all surface <br />artifacts and features. This served to reestablish site <br />boundaries and was a determining factor in the placement of <br />test excavations. Once the site boundary was established, all <br />flagged areas, as well as topographic features, were mapped <br />by transit. The transit data was utilized in the construction <br />of a site contour map. <br />Actual testing procedures varied by site, but certain <br />basic criteria were held in common. Two of the primary testing • <br />methods utilized were the excavation of one by one meter grids <br />and cutbank excavation. These excavations were intended to <br />establish the._presence of subsurface occupation and/or utiliza- <br />tion levels that would be crucial in determining both the <br />length, nature, and extent of the utilization. The presence of <br />these possible levels would be used to assess significance. <br />The location of the test excavations was determined by <br />established concentrations of surface cultural material, topo- <br />graphic situations selected by professional judgment,"and <br />erosional embankments exhibiting gross depositional development. <br />Soils were excavated in a combined effort of shovel skimming <br />• <br />4 <br />
