Archeological studies of pre-historic Arctic cultures are often limited to artifacts and architecture in remote northern environments, leaving large gaps in archeological knowledge. Sediment cores from nearby freshwater lakes and ponds may provide continuous and temporally coherent records of past human occupation, revealing hidden details about past human activities. Canada’s Arctic was home to several cultures, including the Pre-Dorset and Dorset (Paleo-Inuit) peoples (from 2500 BCE until about 1250 CE), and the Thule-Inuit (ca 1200-1600 CE).
