On the Brighton Beach shore of the largest Great Lake — Lake Superior in Duluth, Minnesota — photographer Dawn M. LaPointe captured a stunning natural phenomenon: ice stacking. With the wind blowing during 8°F (-22°C) temperatures, and a thin ice sheet on the water’s surface, the ice pushes up against land, chipping like large shards of broken glass as it stacks and stacks with a crackling sound.
