I used to watch the 20' plus foot waves rolling through Duluth Ship Canal during November (worked right next to it for years). They were so big they just about touched the bottom of our city's famous Aerial Lift Bridge.

Here is a collection of some spectacular photography of Lake Superior storms on the North Shore of Lake Superior in MN if you are interested (https://www.paulsundbergphotography.com/Lake-Superior/Storms). The photographer is the former park manager of Gooseberry Falls State Park.
