west and north peripheries of the impact area. Due to demands elsewhere • at the mine for the motor grader and the exposure of additional cultural features, this phase took three days to o~nplete. Nbnitoring procedures during each of the two phases involved the follow- ing: two archaeologists followed the dozer or grader on either side, carefully observing the backside of the blade for the appearance of artifacts or features (see Figures 6 and 7) ; a third archaeologist prepared recording foans, including maps, so that any featuz:e or artifact mold be recorded and its location mapped as quickly and efficiently as possible; the fourth archaeologist (the field supervisor) shuttled back and forth between the topsoil removal operations and the primary datum coordinating all activities and mapping the features and artifacts exposed by the motor grader. Whenever any cultural feature or artifact was tmoovered, the location was ascertained using the same procedures employed during site mapping. The bearing in degrees off True North frcan the primary dattIIn to an arti- • fact or feature was obtained with a Brunton oanpass and the distance was calculated using a metric tape. The artifact or feature was recorded on the appropriate form and all reco~,ered artifacts were collected. All uncovered features were further defined and cleaned up with trowel and brush and photographed. A few of the host distinctive features were plan view sketched and samples for radiocarbon dating were obtained from those features which contained d~areoal fragments (Fig. 8 ). Once these recordation procedures had been aco~lished, the motor grader was allowed to remove these features. Results. The impact area at SRT139 had all topsoil scraped off to bed- rock, depth to tre latter averaging approximately 50 an, greater depths oa.~urring in the southern portion of the area. The total amount of top- soil displaced is appmx;,rutely 4000-5000 cubic meters. • 36
