Characterizing Provenance of the Late Wisconsinan Rainy Lobe Using Fine-Fraction Geochemistry and Detrital Zircon Geochronology
… glaciation, the sediments reflect long-distance transport from Hudson Bay, and later phases reflect increased proportions of felsic shield lithologies and Duluth Complex rocks with a corresponding decrease in carbonate. These two models of Rainy lobe till sedimentology are evaluated using mixing …

Surface boulder concentrations of the Late Wisconsinan Rainy lobe, Minnesota, USA
… and texture of the underlying till, and mean transport length suggest that this is not the case, and that surface boulder concentrations are primary features of till deposition. We present models for surface boulder deposition in both lodgement till and deforming bed regimes.
