This dissertation explores the inter-relatedness of lithic technology and human mobility in the ancient central North American Arctic. Palaeo-Eskimo populations inhabited southeastern Victoria Island, Nunavut, discontinuously for over three thousand years. During this time, Palaeo-Eskimo lifeways are believed to have changed significantly in regards to subsistence economy, settlement patterns, interaction patterns, and mobility. One of the most significant changes is a marked decrease in the scale and frequency of human mobility and an increase in the re-occupation of seasonal camps. Palaeo-Eskimo material culture is observed to undergo important changes at the same time; consequently, one wonders what influence(s) mobility may have effected on the form and nature of Palaeo-Eskimo material culture. This work examines the potential influence of human mobility on lithic technology in the Pre-Dorset, Early Dorset, and Middle Dorset periods as evidenced by lithic assemblages from nine archaeological sites and site components in the Iqaluktuuq (Ekalluk River) region of Victoria Island. Over 800 formal tools and 30000 pieces of debitage were examined and analyzed according to two interpretive frameworks: one technological and the other mobility-related. The technological analyses demonstrate that significant changes took place in lithic production and maintenance processes during the Palaeo-Eskimo period. The mobility-related analyses demonstrate that, while many of the changes to lithic technological organization are consistent with expected trends resulting from a decrease in human mobility, not all aspects of Palaeo-Eskimo lithic tool production, maintenance and use appear to have been similarly influenced by this change in mobility.

Free and open source geographic information systems (GIS) and spatial data are readily available to use in spatial-archaeological problem solving. Greater accessibility allows more frequent experimentation with archaeological GIS methodologies. The least cost path (LCP) analysis has been a frequently used method in archaeological GIS. Showing potential mobility patterns between archaeological sites or between sites and resources has been the LCP’s primary objective. The LCP’s major flaw is that is must be calculated between two designated points. A recent terrain analysis of southern Baffin Island has been unable to overcome this flaw, because of the size of the study area and the inability to assume any two points are directly related. Thus, a new GIS method using a ‘watershed’ function has been manipulated to incorporate the cost-surface element of the LCP into a mobility model by generating pathway networks instead of narrow A to B paths. The product is a multitude of potential pathways linking archaeologically dense coastal and interior areas. Portions of these pathways correlate with historic geographic descriptions of Inuit travel routes and with areas where chert toolstone is accessible. Generated with no material cost, this analysis has produced a predictive model to help in future research.

L’archéologie de l’Arctique canadien, bien qu’ayant fait une large place à certaines catégories d’objets, telles les têtes de harpon, n’a encore que peu exploité la grande richesse informative des objets en matières dures d’origine animale. Une périodisation typologique a été réalisée sur l’ensemble de la période du Paléoesquimau (~ 4000-500 B.P.), classiquement subdivisée en Prédorsétien et Dorsétien au Canada. Les pratiques techniques et économiques des Paléoesquimaux ont été abordées à partir de l’étude de six sites localisés autour du Golfe de Foxe, région centrale pour l’archéologie arctique : région d’Igloolik (Parry Hill, Lyon Hill, Jens Munk, Freuchen et Kaersut) et nord du Nunavik (Tayara). Les données typologiques et technologiques obtenues permettent de confirmer l’existence d’un continuum culturel entre Prédorsétien et Dorsétien. L’évolution des industries en matières dures d’origine animale observée, notamment au moment du passage du Prédorsétien au Dorsétien, a été interprétée en termes de changements socio-culturels. Un fait marquant serait l’apparition des têtes de harpon à logette partiellement fermée, contemporaine d’une intensification de l’exploitation du morse, témoignant de chasses désormais collectives qui auraient incité les chasseurs à séjourner désormais ensemble dans des habitations plus grandes, occupées sur de plus longues périodes. / The studied ivory, bone and antler artifacts from the Canadian Arctic, only correspond to harpoon heads that served to build the Palaeo-Eskimo chronology (~ 4000-500 B.P.). To ascertain the chronological subdivision between the Pre-Dorset and Dorset cultures a typological study associated with a technological approach was performed. Palaeo-Eskimo technological and economical practices have been derived from the study of six sites located around the Foxe Basin: Igloolik region (Parry Hill, Lyon Hill, Jens Munk, Freuchen and Kaersut sites) and northern Nunavik (Tayara site). The assumption of a Pre-Dorset/Dorset continuum could be confirmed. The observed evolution of osseous industries during Palaeo-Eskimo period (and more precisely the Pre-Dorset/Dorset transition) has been interpreted in terms of socio-cultural changes. The observed technological changes (i.e. harpoon head hafting) could be associated with new patterns of raw material exploitation (diversification in the selection of materials and anatomical elements, as well as functional categories). They testify to the important socio-cultural changes (collective rather than individual hunting) already observed in the settlement patterns (aggregation of the humans in larger houses for longer time periods).

The faunal remains from four archaeological sites on the northwest shore of Mingo Lake, in the interior of Southern Baffin Island, are examined in this thesis. All four sites are radiocarbon dated to Pre-Dorset times (4500 – 2700 BP). The faunal assemblage is dominated by caribou remains. As such, this study is the first, large-scale faunal analysis of an interior Pre-Dorset site with caribou as a main subsistence resource. In total 18,710 faunal bones were examined. Elemental frequencies, fracture patterns, bone burning, and butchering patterns will provide important insights into the lifeway of the Pre-Dorset. The results of the thesis indicate that the Pre-Dorset were utilizing the Mingo Lake area during the late summer into early fall. The main activity at all four sites was caribou hunting with a focus on marrow extraction. The sites served dual purposes as habitation and butchering sites and were occupied for varying lengths of time.
