Great pics,
having cruised on the great lakes and in the Atlantic, I have scarier memories in fresh water!

That's some crazy stuff.

They kinda look photo shopped to me. Maybe I'm wrong.

They were taken near an inlet with a big concrete pier. The waves deflecting back off of the pier made for some spectacular shots. No photoshop, but also not exactly what you would find out in the open waters.

Erie is not a "lake".... it's an inland sea. Spent enough time on it to respect it, a lot.... especially the shallow end....

Hopefully these were taken with a large telephoto lens and not from the fly bridge.
