Level 7 contained the most debris piles (a total of four), and most of these appear to extend outside the Main Block. More debris piles in Level 7 correspond to more stone tools and more stone debris in general, suggesting more tool making. This goes along with greater quantities of other materials in Level 7, such as shells, animal bones, and burned rocks, all of which points to more-frequent use of the campsite (Figure by Sandy Hannum, Prewitt and Associates, Inc.). |
