investigation was sufficient to detect any sites larger than <br />those represented by a few flakes. Also, closer spacing of ~~ <br />crew members would have required more than 30 man-days per sec- <br />tion at a cost much higher than the 5 man-days per section fig- <br />ure used in the cost estimate for the project. As it turned out, <br />heavy vegetation cover in parts of the mine site increased the <br />survey time to an average of approximately 8 man-days per section. <br />It is believed that the higher cost of closer spacing of crew <br />members outweighs the marginal benefits that might accrue, at <br />least in the present case. whenever some evidence of cultural <br />occupation was encountered by one of the crew, the other crew <br />members made an intensive search of the local area. If more than <br />six flakes were found, a site form was filled out either by the <br />principal investigator or by one of the crew members under his <br />_ - direct supervision while other members of the crew continued to .. ___ • __. <br />search the area or took photographs as directed. Site locations <br />were mapped on 7~' USGS quad sheets. Individual finds were <br />usually not mapped within the site area because it was felt that <br />the information obtained would not justify the time required to <br />do the mapping, at least within the context of a site inventory. <br />Controlled surface collection on a site gridded off in squares <br />..•r... bf predetermined size and tied into a datum point, however, is <br />en important information recovery technique used in further in- <br />;. vestigation of sites that cultural resource inventories identify <br />• as having significant.archeological potential. <br />.~ <br />
