60 <br />• Site Density <br />The site density index, tabulated on Table 12, is a quantitative <br />measure of the number of sites relative to the surveyed area within each <br />tract. It has been calculated by dividing the number of sites within the <br />tract boundary by the intensively surveyed acreage for that tract and <br />multiplying by 1000. This index figure provides a means to rank one tract <br />against another, in terms of the number of sites present in areas which <br />appear to be adequate for habitation. It is necessary to keep in mind <br />that since the sampling technique was by no means random, the density <br />index value is not a predictive measure. <br />The number of sites tabulated in Table 12 does not include sites <br />adjacent to but outside the tract boundaries. Sites located in other <br /> <br />surveys, especially those recorded by CU in June of 1975, are included <br />~• since they make up part of the cultural resources present in the study <br />area. This applies to Tracts 8, 13, and 14. <br />Overall, the site density index averages 5 (4.55), which corresponds <br />to an average site density of roughly one site per 450 to 500 ac. Tract <br />7, with an index figure of 10, skews the mean value somewhat, as more <br />sites were located in a smaller area than any other tract. Tract 8, al- <br />though it contains eight sites within the tract boundary, has a. much <br />lower density index due to the larger area surveyed. In this case, espe- <br />cially, the site locations generally fall near water, the Yampa River, <br />but much of the surveyed area was at a considerable distance from any <br />available water source. It seems likely that the lower density index <br />also reflects the unequal distribution of the sites within the surveyed <br />. area. <br />
