It is hard to believe that two months ago, Valerie and I walked across these same ice cliffs along the shore of Whitefish Point on Lake Superior. That time the lake was frozen as far as the eye could see. The cliffs were still over the past weekend, but they had shrunken significantly. The sand that the winter wind had stirred up and had been captured in the freezing ice piles has now become exposed to the warming air and the ice is covered with a thin layer of sand and small stones. In a month, all this will most likely have melted and the beach will return to its warm-weather appearance.
