In the fall of 2022, on behalf of Alberta Parks, a Historical Resources Impact Mitigation of two archaeological sites (GfOx-59 and GfOx-61) was conducted on the Big Island of Sir Winston Churchill Provincial Park in Lac La Biche Alberta.  These sites contained two different ceramic assemblages, with GfOx-59 producing Narrows Fabric Impressed Ware, first identified in the Buffalo Narrows region of Northwestern Saskatchewan, and the ceramic ware most common in the region.  While GfOx-61 produced Avery Horizontal Corded Ware, first identified in southeastern Manitoba, and never before observed in northeastern Alberta.  Both wares are discussed and their distributions across western Canada examined.  It is posited that with the newly confirmed presence of Avery Corded ware within northeastern Alberta, past ceramic sherd identifications may have combined the relatively similar morphology of body sherds due to a superficial or untrained inspection, and that some previously collected assemblages could potentially contain unrecognized Avery Horizontal Corded Ware.  If confirmed the presence of this ware across the region could then indicate a previously undiscovered cultural expression in the region, or a long distance trade and influence network stretching from southeastern Manitoba to northeastern Alberta.

The Tillsonburg Iroquoian village was excavated by three CRM companies between 2000 and 2018, revealing 16 house structures distributed over 18 hectares (44 acres). The houses are distributed in a dispersed clustered pattern with easterly, central, a southwesterly and northwesterly house clusters, none of which are palisaded. Following an initial analysis of the westerly section by Timmins (2009), a detailed analysis of ceramics and settlement patterns on the west and east sections was conducted by Rebecca Perry (2017, 2019) who established that there is some time depth to the Tillsonburg village, with the easterly house cluster dating relatively earlier than the westerly houses. To refine the chronology, a series of 11 AMS dates were processed on short lived samples (maize kernels and deer bone) from house features and subsequently subjected to Bayesian analysis. The results suggest that the village dates to between ca. AD 1379 and ca. AD 1415. This paper discusses the radiocarbon results and makes a series of inferences about the internal chronology of the village.
