Winter reveals the true contour of the dunes along Lake Michigan's Indiana shore. There is quite a difference between the contour of the ground and the treetops. Water and nutrients collect in the small valleys between the dunes, and the trees benefit from this extra moisture, growing taller and stronger. Trees near the top of the dunes appear to be a bit more stressed, from the lack of moisture, nutrients and the elements.
