Crashing over rugged basalt cliffs, the booming churn of the Pigeon River obscures that imaginary line somewhere inside, marking the Ontario/Minnesota (Canada/U.S.) border. Seen here from the better vantage on the Canadian side, the rugged basalt cliffs and blocks rip the water into a tempestuous froth of drops, spray and wildly gyrating splashes. This paints a refreshing image on a hot summer day, but the falls themselves are too intense and potentially rock-bearing for anyone to swim beneath.
