This paper reports on a small arctic flora from full-glacial sediments exposed in the Jore-1 site in southeastern Minnesota, an area not covered by late Wisconsinan ice.

A study of Wisconsinan loess in part of southeastern Minnesota confirms earlier suggestions that much of the loess in this region was not derived from the floodplain of the Missisippi River. Two Wisconsinan loess units, the Peoria Loess and Roxana

The composition, magnetic characteristics, and pollen content of sediments from two small kettle lakes near the prairie-forest border in west-central Minnesota were used to infer changes in terrestrial vegetation, shoreline erosion, eolian inputs

The Minnesota tunnel valleys are composed of individual segments 10-20 km long, and the segments commonly terminate in subaerial outwash fans at recessional ice margin positions. Eskers, associated with the tunnel valleys, are also composed of short
In an effort to define the parent lobe of the deposits in central Minnesota, the tills are sampled, analyzed, and compared by graphical and multivariate techniques. Graphical comparisons of sedimentological parameters are inadequate to distinguish

Results of stratigraphic charcoal analysis from thin sections of varved lake sediments have been compared with fire scars on red pine trees in northwestern Minnesota to determine if charcoal data accurately reflect fire regimes. Pollen and opaque
