Accurately reconstructing the rate of movement and extent of eolian dunes over thousands of years is a challenging endeavor. In this paper, we refine the methodology for utilizing lakes and bogs downwind of dune fields as precise recorders of past eolian activity. Sediment cores from two Allegan County lakes and one bog associated with dunes were studied to evaluate the importance of the various sand transport pathways into lakes and bogs. Goshorn Lake's western edge directly abuts a large parabolic dune. Sand concentrations decrease in cores away from the dunes, possibly reflecting avalanching into the lake followed by sediment gravity...
