The chipped-stone tool assemblage contains a variety of tool classes, including small triangular projectile points, drills, perforators, retouched flakes, utilized flakes, scrapers, choppers, and chipped stone disks.
Of the 2,761 flakes analyzed, 134 showed evidence of use along at least one edge. The edge damage on the flakes indicated that most had been used for scraping or cutting. Secondary decortication flakes (33%) and interior flakes (56%) were most often selected for retouch or use.
A large number of other flakes also exhibit retouch along at least one edge. Because retouch is confined to the flake edges, flake morphology is evident on these tools. Similarly, a few scrapers, characterized by formalized retouch, are also present. This retouch usually resulted in shaping the tool so that it has a symmetrical convex working edge. These tools apparently were used in scraping and cutting.
The few drills and perforators present in the assemblage were constructed on flakes and are not highly formalized tools. One exception is a drill that appears to have been recycled from a small triangular projectile point. Overall, these tools appear to have been expediently manufactured on flakes. Flaking is primarily unifacial, and restricted largely to the bit end. Some of these tools also exhibit flaking along the base, presumably to shape the tool for hafting. These tools were probably used to punch or bore holes.
Other chipped-stone tools include several large choppers ranging from 6 to 22 cm in length. These tools were made from local, platy phyllite that had been roughly chipped along the edge to only slightly alter the natural shape of the stone. The shape and edge characteristics of these tools suggest that they were used in heavy-duty tasks such as digging or chopping.
Seven chipped-stone disks were recovered from five features. The raw materials from which they were manufactured include fine-grained granite, argillite, soapstone, and schist. They range in diameter from about 40 mm to 100 mm, are made on non-cryptocrystalline stone, and are roughly chipped into a circular shape. Several other broken and unidentified ground-stone disks and polished cobbles are also present. All were recovered from feature contexts, and the function(s) of these artifacts is unknown.
