The Nipissing transgression around 5,000 years BP resulted in an increased wetness at the site with a transition to bog vegetation and peat accumulation. This bog was periodically inundated by minor transgressions. Ultimate regression of Lake Nipissing exposed the site to a period of eolian activity, prior to the development of a stable plant community. A survey of surlicial sediments within the surrounding area supports the established history of the basin and enhances on-site conclusions. During the Archaic Period, people were occupying the Lake Nipissing shorelines. Because of fluctuations in the level of Lake Nipissing, nearshore archaeological sites are scattered over broad areas in a thick accumulation of sediment, rather than being concentrated near traditionally mapped beaches.enPlan As (thesis-based master's degrees)Department of Earth and Environmental SciencesUniversity of Minnesota DuluthMaster of ScienceMaster of Science in GeologyReconstruction of the Late Glacial and Holocene Paleoenvironmental Setting at 20SA596, and the Saginaw Basin, MichiganThesis or Dissertation
