The so-called pancake ice in Grand Marais' harbor undulated like curly edged Arctic lily pads, wavering in the wind and waves. Orange tones of sunset glinted across the frozen discs and Lake Superior's steely blues.
Despite hand-numbing January temperatures, this could be one of Minnesota's most mesmerizing sights. The play of light and the movement of the ice made the lake seem more alive than usual. It inhaled and exhaled waves that struck the harbor's breakwater, ringing it with icicles.
Winter admirers picked their way across slippery rocks and snowy drops for the best views, and to check out glassy shrubs and rocks piled with ice.
Lake Superior's shoreline show can continue after dark with the moonrise, a crisp view of constellations and the possibility of Northern Lights.
Aurora forecast apps and the Space Weather Prediction Center website (swpc.noaa.gov) can help you pinpoint celestial activity, and weather reports make guesses on wind, snow and temperatures that constantly repaint the lake like a blank canvas.
Changing conditions can cause a placid surface to eerily give off steam at sunrise, or encase the harbor in ice, or whip up waves and pile jagged pieces of ice onto the shore. The "pancake ice" patties form when floating chunks collide, rounding their edges and building up ridges of slush.
By morning, the almost perfectly rounded pieces were gone, whisked away by a lake that changes its mind as often as the weather.
