The Dog Child site is a multi-component archaeological site located within Wanuskewin Heritage Park, approximately three kilometres from the City of Saskatoon, Saskatchewan. The site was excavated from 2004 to 2009 during the summer field season with help from the University of Saskatchewan Department of Archaeology and Anthropology field school and the Saskatchewan Archaeological Society field school. A Master of Arts thesis dealing with the first three years of excavation entitled The Dog Child Site (FbNp-24): A 5500 Year Multicomponent Site on the Northern Plains was completed by Cyr (2006).<p> A focus on the 2007 to 2009 field seasons has been undertaken in this thesis. Artifacts including projectile points and pottery recovered from the site as well as radiocarbon dates confirm the presence of six occupation levels. Five different projectile point series or complexes are associated with the six occupation levels including: Plains Side-Notched, Prairie Side-Notched, McKean series, Oxbow complex, and Mummy Cave series (Gowen). The Mummy Cave series at the site encompasses two of the occupation levels identified. Due to the rich Gowen cultural level at the site the opportunity to study this cultural occupation in more detail became the focus of the second research program.<p> The Hypsithermal is a period of increased complexity and debate on the Plains. This thesis focuses on the 7500 to 4500 years B.P. time frame during which Mummy Cave series cultural occupations are present. The archaeological remains recovered from the Gowen occupation at the Dog Child site suggest the utilization of a broader subsistence base rather than a sole focus on utilizing and consuming bison. Comparison of other sites from this time period indicates that the Dog Child site may be unique in the number of specimens and taxa represented by the excavated faunal assemblage. From this analysis a wealth of new archaeological data including insight into Hypsithermal subsistence patterns and paleoenvironmental studies can be observed.

A 7.09 m lacustrine sediment core was taken from Mariana Lake, Alberta (55º57'N, 112º01'W) to determine if the regional vegetational complex had been affected by the mid-Holocene Hypsithermal. Dating control was provided by 6 radiocarbon dates, with a second degree polynomial fitted to the dates to give an age to depth curve. The basal date of the core is 11 300 ± 110 yr BP. Fossil pollen analysis of the core revealed five distinct pollen zones. Between 11 856 and 10 434 yr BP the study site supported a sparse herb dominated vegetation. A spruce and shrub birch assemblage followed, from 10 434 to 9 100 yr BP, with increased vegetation density. The climate was likely similar to today. This was replaced by a paper birch and spruce complex from 9 100 to 7 638 yr BP likely as a result of warming climate. A mild Hypsithermal effect is recorded between 7 638 and 5 623 yr BP. A forest of decreased crown density was created, with spruce, paper birch and poplar being the major vegetational components. Modern conditions have existed at the site from 5 623 yr BP onwards, though it is hypothesised the regional water budget may have increased slightly around 2 228 yr BP; increased peat development appears to have occurred at this time. Through the use of difference diagrams the site is compared to three other published sites which, along with Mariana Lake, form a north-south transect from the southern Boreal Forest to the northern Alberta Boreal Forest. The hypsithermal vegetation changes varies with distance to the Parkland-Boreal Forest ecotone boundary. It is concluded the parkland did not reach Mariana Lake during the mid-Holocene, though conditions at the site became similar to those at the southern edge of the Boreal Forest that is proximal to the parkland. / Thesis / Bachelor of Arts (BA)

Ten sediment cores (2.0-8.5 m long) from various locations in Lake of the Woods (LOTWs) and Shoal Lake (SL) were recovered in August 2006, using a Kullenberg piston corer. From the study of the macrofossils (primarily ostracodes and thecamoebians) and the sediments in six processed cores, variations in paleoconditions were observed both spatially and temporally, and the timing of these changes were identified in over 10,000 years of postglacial history. Ostracodes disappeared from the LOTWs record from about 9000 to 7600 calendar years before present (BP) (about 5800 in SL), after LOTWs became isolated from glacial Lake Agassiz. Thecamoebians appeared in many cores around 2000 calendar years BP, with the earliest appearance at 9200. Buried paleosols in three cores indicate portions of the lake dried on several occasions during the Hypsithermal, perhaps indicating the region’s future climate response. One core contained a pink clay bed indicative of the Marquette readvance about 11,300 years (BP), and the subsequent input of water from the Superior basin.

This thesis assesses climate change during the Hypsithermal Climatic Interval through the analysis of freshwater mussel remains from archaeological sites in Eastern North America. Modern climate data was used as a model to test the mosaic consequences of climate change. Freshwater mussels: can be used as indicators of precipitation by examining changes in overall size through time: larger mussels are found in larger streams, while smaller mussels are found in smaller streams. This study combines morphometric and isotopic data from archaeological freshwater mussels at Modoc Rock Shelter, Watson Brake, Plum Creek, Owens site, and Landerneau mounds to assess past climatic conditions. At Modoc Rock Shelter, oxygen isotopic data corroborate morphometric data and show that climate was fluctuating with a period of stability at the onset of the Hypsithermal. The oxygen isotopic data sets from the Louisiana sites show that the mid-Holocene was much warmer than the late-Holocene.
