Waves of ice clashed against the shoreline of Lake Superior in Ashland, Wisconsin, on December 16.
Photographer Cheryl Koval, who lives on the shore of Lake Superior, captured the sight, sharing a number of videos to YouTube on that date.
“This is so cool,” she wrote in the caption to one video, with the icy conditions creating “awesome icy waves” as well as “pancake ice” on the waters.
A tweet from a local National Weather Service noted on December 16 that temperatures dropped to 19 degrees Fahrenheit (-7.2 degrees Celcius) between midnight and 6 am due to the wintery conditions. Credit: Cheryl Koval via Storyful
