Pollen and charcoal analyses of lake and bog core sediments from Voyageur`s National Park and the Apostle Islands National Lakeshore provide evidence of regional Holocene climate changes for the western Great Lakes that differ from paleoclimates interpreted for regions of the Midwest more distant from the Great Lakes. The timing of the middle Holocene dry period when prairie and oak-savannah expanded in the Midwest occurs between 9000 and 5000 yr B. P. in the northern regions, but between 5600 and 3500 yr B.P. in the lower tier of the northern midwestern states away from the lakes.
