"Crude pottery vessels and potsherds were discovered associated with the objects of stone. This ware incorporates elementary decorative designs distinct from the known historic Eskimo or Indian types of pottery decoration. There can be no intimation that this ware is archaic or that it belongs to any archaic culture offshoot from farther south. It therefore becomes a question of some unknown earlier Asiatic culture connection that manifested itself in crude forms of flaked and ground stone implements and in unique pottery forms. It is uncertain that the ancient fossil ivory culture of northwest Alaska, of which Doctor Hrdlička has brought in some excellent examples, is in any manner associated with the primitive neolithic stone and pottery forms uncovered at Bonasila. It is established, however, beyond a doubt that both cultures and types of artifacts are Asiatic in origin and have little or no connection with the culture of the western Eskimo. "The Eskimos of the lower Yukon Valley made extensive use of slate and of jadeite in the production of their polished knives and celts. Slate knives and polished celts of jadeite are characteristic of Eskimoan culture throughout the whole of its extent in Alaska. Each of these materials as well as the finished products shaped from them were subjects of native barter. Eskimos often undertook long journeys for their procurement. It is therefore noteworthy that no single object fashioned from slate or jadeite and but few points of fossilized ivory were recovered at any of the sites characterized by the primitive stone culture and pottery of the Bonasila type. "The most characteristic finds at Bonasila are the crudely flaked implements of stone, some of which show incipient chipping and grinding. The coarse type of pottery is unlike that of the modern Eskimo in tempering, firing, and decorative design.
