The test pit explorations were each advanced to an approximate depth of10 feet <br />below ground surface (BGS), while the DCP explorations were advanced to <br />approximate depths of 4.5 to 7.5 feet BGS. Approximate locations of these <br />explorations are plotted on the Site and Exp/oration Plan (Figure 2). <br />2 <br />
