Detecting Early Widespread Metal Use in the Eastern North American Arctic around AD 500–1300

In the first millennium AD, peoples across the North American Arctic began to use and exchange metal. A group known as the Late Dorset (AD 500–1300) were the first to widely exchange metal in the Eastern Arctic. However, due to differential taphonomic processes and past excavation methods, metal objects in existing collections are rare although geographically widespread. This has led to metal being seen as a broadly exchanged but uncommon raw material among Late Dorset. This article expands the known scale of Late Dorset metal use by analyzing the blade slot thicknesses of bone and ivory objects from sites across the Eastern Arctic and comparing them to the thicknesses of associated lithic and metal endblades. These results demonstrate that Late Dorset used metal at least as frequently as stone for some activities. Given the few and geographically discrete sources, metal would have been exchanged over thousands of kilometers of fragmented Arctic landscape. The lack of similar evidence in earlier periods indicates intergroup interaction increases significantly with the Late Dorset. It is through these same vectors that knowledge and information would have flowed. Metal, consequently, represents the best material for understanding the maximum extent and intensity of their interaction networks.
