Biogeochemical analysis of total mercury (tHg) and d13C/d15N ratios in the bone collagen of archaeologically recovered marine fauna from coastal Alaska shows high tHg levels during early/mid-Holocene (ca. 52-4600 rcy BP). This is linked to glacial melting and sea-level rise at the end of the Pleistocene. Under current conditions of climate warming, these processes may lead to future increased Hg bioaccumulation in marine species and by extension their human consumers. I discuss the value of length time series for understanding ecosystem structure and function and change over time, and the connections among ocean processes, sea level rise, and prehistoric human health and future health risks.
Dr. Maribeth Murray is the Executive Director of the Arctic Institute of North America and Professor of Archaeology at U Calgary. She came to Calgary in July from the International Arctic Research Institute of the University of Alaska Fairbanks where she was the Executive Director of the International Study of Arctic Change (ISAC). As Executive Director of ISAC she was responsible for the growth and development of an internationally supported, ongoing program of arctic environmental change research, science planning, and stakeholder engagement. She has worked in the Arctic and subarctic for over 20 years where her research is focused on climate change and human and marine system dynamics. She holds a BA in Archaeology from Wilfrid Laurier University in Waterloo, an MA in Archaeology from Memorial University of Newfoundland, and a PhD in Anthropology from McMaster University. Dr. Murray serves on a number of polar advisory committees, including that of the Swedish Mistra Foundation’s Arctic Futures program, the EU Svalbard Integrated Earth Observing System science advisory board, and the US Study of Environmental Arctic Change (SEARCH) observing change panel.

Most cultural resource management (CRM) projects undertaken in the eastern slopes of Alberta are focused on spatially constricted developments such as road alignments, forestry cutblocks, petroleum pads and pipelines. Often the evaluation of archaeological potential for these projects is focused on geographic constraints in the immediate vicinity of the development (e.g., proximity to water, local topography and soil properties). This paper examines broader scale geographic characteristics that influence the movement of people through the eastern slopes, focusing on the connections between hinterland site locations and resource procurement destinations (e.g., major lakes, lithic sources, alpine environments). Case studies from the Lick Creek Basin, Willmore Wilderness Park, Kakwa Wildland Park and Musreau Lake will be presented. These case studies highlight the use of digital terrain analysis and lithic raw material studies in identifying links between site location and resource procurement destinations.

Sunwapta Pass and the Athabasca Glacier are visited by thousands of people each year as they travel the famed Icefields Parkway, following in the footsteps of the first tourists who marvelled at the glacier in the late 19th century. Easy to access, the area has also been intensively studied by geoscientists and palaeoecologists. Within its small compass, it exhibits considerable diversity of landforms, vegetation, and bedrock. Here, we can find stories of mountain building, ancient volcanoes, flowing ice, tilted trees, climate change and adventurous travellers.

During the course of investigations in support of the Hanna Region Transmission Development for Atco Electric Ltd, a hitherto unknown complex of Precontact era sites was encountered in an area southeast of Consort known as the “Misty Hills”. We have identified an extensive group of sites, consisting of at least one large quarry area with pebble chert and pebble quartzite deposits where toolstone was tested and gathered, together with a number of associated workshop/lookouts and workshop/campsites. A unique aspect of the Misty Hills quarry is that both high quality chert and quartzite pebbles can be found here, and both were apparently used by ancient peoples. Assemblages are characterized by high densities of un-tried and tried quartzite and chert pebbles, with scattered anvils and hammerstones. The Misty Hills are a relatively dense nexus of extremely well-preserved examples of different types of sites that reflect on different aspects of ancient life. The significance of the quarry, workshops and campsites in the Misty Hills is greater than the sum of its parts. In recognition of this significance, ATCO engaged in project re-design in a commendable effort to avoid impacts to these significant sites.

The Viking Age settlement at the site of Birka, Sweden, is touted as the first major city of Sweden. This UNESCO world heritage site was uniquely placed at a crossroads of international trade and enjoyed prominence from approximately 650-900 AD. Excavations at Birka 2013 focused on excavating and recording piling timbers deposited in the bay, which formed the Viking age harbour, in an attempt to better understand the harbour structure and shipping industry. The project comprised the systematic excavation of a 3m by 2m trench, removal and recording of piling timbers with constructional features, sampling of the timbers for dendrochronology, and underwater core sampling of the bay. The project was conducted by Sjöhistoriska (Swedish Maritime Museum) with an international crew of maritime archaeologists from Sweden, Denmark, Finland, Germany, USA, and Canada. The 21 day excavation revealed a clearer picture of the harbour structures and unearthed a number of domestic artifacts as well as high status jewellery. The nature of submerged sites allows for the preservation of organic material that would not survive on land and so the artifacts found during this excavation have contributed to an understanding of Birka that would have been lost on land. This presentation will explore the history of Viking age Birka and present the findings of the 2013 excavation, as well as discuss the methodologies associated with conducting archaeological investigations underwater.
