Characterization of chert artifacts and two newly identified chert quarries on Southern Baffin Island

Abstract Inductively coupled plasma-mass spectrometry (ICP-MS) trace element analysis was used to characterize raw chert from one secondary (LeDx-42) and two primary (LbDt-1 and LdDx-2) sources on southern Baffin Island, Nunavut, Canada. Raw chert trace element data are compared to ICP-MS trace element data for chert artifacts from a nearby Palaeo-Eskimo archaeological site (LeDx-42). Geochemical consistencies identified among the analyzed samples support the inference that Palaeo-Eskimo toolmakers at LeDx-42 exploited LdDx-2 and LbDt-1 as chert source locations.

A human-centered GIS approach to modeling mobility on southern Baffin Island, Nunavut, Canada

Southern Baffin Island has been occupied for several millennia, but its enormous size, coupled with scarcity of identified inland archaeological sites that can be confidently linked to coastal occupations, makes modeling ancient seasonal mobility across the region through traditional cost-surface least-cost pathway approaches impractical. We present a method that combines weighted multi-criteria cost surface analysis with a watershed function to create a “mobility-shed” of non-winter travel pathways covering the study area. We evaluate the predictive utility of the resulting pathways for future archaeological survey by assessing their spatial relationships to known archaeological sites. The results of this comparison suggest that elevation and land cover criteria should be augmented with ethnographic and resource availability data to model mobility in this region.

Faces from the Franklin expedition? Craniofacial reconstructions of two members of the 1845 northwest passage expedition

In 2013, partial skeletal remains from three members of the 1845 John Franklin expedition were recovered from an archaeological site at Erebus Bay, King William Island, Nunavut. The remains included three crania, two of which were sufficiently intact to allow craniofacial reconstructions. Identifications are not proposed for either reconstruction; however, tentative identifications are being explored through DNA analyses currently underway that include samples obtained from both crania.

Franklin expedition lead exposure: New insights from high resolution confocal x-ray fluorescence imaging of skeletal microstructure

In the summer of 1845, under the command of Sir John Franklin, 128 officers and men aboard Royal Navy ships HMS Erebus and HMS Terror sailed into Lancaster Sound and entered the waters of Arctic North America. The goal of this expedition was to complete the discovery of a northwest passage by navigating the uncharted area between Barrow Strait and Simpson Strait. Franklin and his crew spent the first winter at Beechey Island, where three crewmen died and were buried. In September 1846, the ships became stranded in ice off the northwest coast of King William Island, where they remained until April 1848. At that time, the crew, reduced to 105, deserted the ships and retreated south along the island’s western and southern shores in a desperate attempt to reach the mainland and via the Back River, to obtain aid at a Hudson’s Bay Company Post. Sadly, not one individual survived. Previous analyses of bone, hair, and soft tissue samples from expedition remains found that crewmembers’ tissues contained elevated lead (Pb) levels, suggesting that Pb poisoning may have contributed to their demise; however, questions remain regarding the timing and degree of exposure and, ultimately, the extent to which the crewmembers may have been impacted. To address this historical question, we investigated three hypotheses. First, if elevated Pb exposure was experienced by the crew during the expedition, we hypothesized that those sailors who survived longer (King William Island vs. Beechey Island) would exhibit more extensive uptake of Pb in their bones and vice versa. Second, we hypothesized that Pb would be elevated in bone microstructural features forming at or near the time of death compared with older tissue. Finally, if Pb exposure played a significant role in the failure of the expedition we hypothesized that bone samples would exhibit evidence of higher and more sustained uptake of Pb than that of a contemporary comparator naval population from the 19th century. To test these hypotheses, we analyzed bone and dental remains of crew members and compared them against samples derived from the Royal Navy cemetery in Antigua. Synchrotron-based high resolution confocal X-ray fluorescence imaging was employed to visualize Pb distribution within bone and tooth microstructures at the micro scale. The data did not support our first hypothesis as Pb distribution within the samples from the two different sites was similar. Evidence of Pb within skeletal microstructural features formed near the time of death lent support to our second hypothesis but consistent evidence of a marked elevation in Pb levels was lacking. Finally, the comparative analysis with the Antigua samples did not support the hypothesis that the Franklin sailors were exposed to an unusually high level of Pb for the time period. Taken all together our skeletal microstructural results do not support the conclusion that Pb played a pivotal role in the loss of Franklin and his crew.

Retracing the route of Hans K. E. Krüger's 1930 German Arctic expedition

Prior to the discovery in 1999 of an archaeological site near Cape Southwest, on southern Axel Heiberg Island, little was known about the movements of the ill fated 1930 German Arctic Expedition, led by Hans K.E. Kruger. What was known was based on the content of three cairn documents that spanned a period of just thirteen days. This paper presents new information that expands our knowledge of the expeditions route using catalogue labels found with geological specimens collected by Kruger and recovered from the site. The movements of the expedition over a period of 43 days are reconstructed, ten additions are made to the known itinerary, and an approximate date of the groups arrival at Cape Southwest is presented. The data show that despite concerns about the health of both Kruger and his Danish assistant, and about the weight of equipment being transported, the expedition had made good progress prior to reaching Cape Southwest.
