Connection to the quarry pit

An important question remains concerning the history of the Q02-2 quarry pit that lies 600m uphill to the east of the workshop. Due to a lack of datable materials or diagnostic artifacts in the quarry pit test unit Q02-2u2, it was not possible to directly link excavation levels at that unit with activities and excavation levels at the workshop test unit Q02-2u3 on a temporal basis.

If large nodules were being transported from the quarry to the site of A03-126 where they were being reduced, the morphology and visual characteristics of cortical flakes in Q02-2u3 may reflect this import of cores from the quarry pit up the hill. These tables can be compared with data presented earlier in Table 7-9 and Table 7-11 from the quarry pit test unit.

Table 7-26. Q02-2u3: Length of complete flakes and cores with ?50% cortex.

In comparing these data with the tables discussed earlier from the Q02-2u2 quarry test unit, no specific pattern is apparent that decisively links the quarry pit with the workshop downslope. An increase in Clear and Clear-Banded obsidian becomes visible in level 3 of the workshop (q02-2u3), in Table 7-10 shown above, that could reflect a sudden availability of this material from excavation at the quarry pit provided that the quarry pit is the sole source of this clear and clear banded obsidian. However as mentioned, the quarry pit is probably not the sole source of clear obsidian because it contains proportions of clear obsidian that reflect tool use over the entire region. There was concurrently a decrease in other colors of obsidian in level 3. No discrete pattern was observed in the Ob1 vs Ob2 material type linking the two pits. Finally, the length of cortical flakes indicates that dramatically more long flakes were deposited at the source from level 5 onwards, as discussed earlier, but there were also notably more medium and small cortical flakes in those levels as well.
