<br />lz <br />The survey crews were normally composed of three to five members <br />distributed roughly at fifty meter intervals. This spacing varied accord- <br />ing to the terrain and vegetation. The goal was to obtain maximum dis- <br />persal while maintaining adequate surface coverage. Additional effort <br />was expended in localities where sites would likely occur: on saddles, <br />drainage confluences, stream terraces, interfluvial ridges, and sheltered <br />areas. <br />In summary, each tract was divided into 40 ac. quadrants to facili- <br />tate map evaluation. This led to determining which areas were worth <br />surveying and which could be safely eliminated. Criteria for suitability <br />were established on the basis of grade, aspect, and vegetation. Areas <br />with grades exceeding 15%, and having a northerly aspect or excessive <br />vegetation, were subject to visual field check. However, these areas <br />were not as intensively surveyed as areas that met LOPA's criteria. <br />After a field check for clearings which might merit surveying, heavily <br />vegetated areas were eliminated from further survey when the vegetation <br />density was impossible to penetrate or when the ground was so completely <br />covered that cultural materials could not be seen. <br />DEFINITIONS <br />Definition of Site <br />The term site has received much varied treatment in archaeology. <br />The concept has been operationalized for the purposes of this project <br />. in the following way: <br />
