Abstract: 

Full-glacial pollen assemblages from four radiocarbon-dated interstadial deposits in southwestern Ohio and southeastern Indiana imply the presence of herbaceous vegetation (tundra or muskeg with subarctic indicator Selaginella selaginoides) on the southern margin of the Miami lobe of the Laurentide Ice Sheet ca. 20000 C-14 yr BP. Scattered Picea (spruce) and possibly Pinus (pine) may have developed regionally ca. 19 000 C-14 yr BP, and ca. 18 000 C-14 yr BP, respectively. Spruce stumps in growth position support a local source of pollen. Prior to the ca. 14 000 C-14 yr BP glacial advance, small amounts of Quercus (oak) and other deciduous pollen suggest development of regional boreal (conifer-hardwood) forests.
