Figure 2.3 Prehistoric archaeological sites vs. Area surveyed in square miles for each physiographicregion in southeastern New Mexico; physiographic regions are numbered according to area in SE NewMexico from smallest to largest: 1 = Southwest Pecos Slopes, 2 = Portales Valley, 3 = Canadian RiverDrainage, 4 = Pecos River Valley, 5 = Northern Pecos Slopes, 6 = Mescalero Plain, 7 = Llano Estacado,8 = Sacramento Section; total 9,256 archaeological sites; total surveyed area is 915.61 square miles;dashed regression line; Inset Diagram is same data converted to log values; regression line andcorrelation coefficient show strong positive correspondence; a doubling of survey area results in adoubling of the number of sites.Figure 2.4 Number of sites vs. Area surveyed in square miles for each of the geoarchaeologic mapunits in southeastern New Mexico; regression line and correlation coefficient show strong positivecorrespondence regardless of geoarchaeological status; at coarse-scales, a doubling of survey arearesults in a doubling of the number of sites.2-16
