"All of the Great Lakes including Lake Superior are now ice free. This marks the end to a 7 month stretch where the lakes were covered in at least one ice cube, which is the longest streaks since satellite records began back in the 70’s. June 7th became the official ice out date of the lake which also makes in the latest in the year ice has coated the water. There was still a third of the Lakes coated in ice the last week of April which was the largest amount of ice that late in the year, a trend that continued into June."
