She is also over 1,300ft/400m deep at her deepest. Once she has eaten you, she will not give you back. Lake Superior doesn't give up her dead.
And when Bunjy says "the largest by surface are" what that means is: Lake Superior is a whopping 31,700 square miles (82,103 square km) of water. The only reason she is not an inland sea is because she is freshwater.
She has tides. She has rip currents, like an ocean does. You don't even have to go out on a boat to get got by her, all you have to do is step into her icy waters in the wrong spot. She has ice formations that aren't "icebergs" on the technicality that they didn't calve from glaciers, even though they look and act the same.
She LOOKS like an ocean when you are at her shores. This is from a location on the Minnesota side shore.

She is huge, icy, and hungry. This makes her very dangerous. Not to be fucked around with, because you WILL find out.
