In this Oct. 25, 2011, photo, workers use an excavator and bulldozer to work in the Le Sueur River to stabilize river banks with large tree trunks near Mankato, Minn. Researchers in southern Minnesota are hoping a photo a day will show where the bluffs are washing away in the Le Sueur River watershed.
