I keep finding myself going back to these images from January 2015. In this photo, the ice sheets extend out into Lake Huron, near Point Clarke, to about 2 miles. The weather had been relatively mild for January, but a sudden deep freeze caused the thin ice to pile up and rapidly freeze into an extended, but thin “shelf”. Because the open water beyond the shelf was still relatively warm, moisture laden air rose up into the dark snow clouds you see in the distance. It was sunny where I was standing, which lights up the snow and ice nicely, but is a strong contrast to the snowstorm occurring off-shore.
