Has there ever been a case in the past 100 years where one of the Great Lakes COMPLETELY froze solid to the extent that one could hike on foot from USA to Canada?

I remember when I lived in Cleveland in the real cold winters of 76/7/8 that happened for Lake Erie. It was dicey, because there were areas that didn’t freeze completely.

And IIRC there were a number of Coast Guard rescues of people who got trapped by open water.

My father claimed he walked across a frozen St Clair River from Port Huron to Sarnia, which would be a short walk if the river was safely covered in ice. That would have been in the 1930’s. Nowadays they use ice cutters to ensure waterborne freight keeps moving

Lake Erie has frozen over completely several times, latest in 1996. You could have walked to Canada, but it would be a very long cold walk, and for what...it's just colder up there.
