greg,

It was a wide inlet from the sea, one of the few I visited in Norway that did not have mountains coming down to the water. Standing on the rock shelf, I looked out over what seemed a flat expanse of water- until I noticed small waves, about 6 inches high, running is several directions. At the same time. Not quite a whirlpool, but very fast moving water, some going out to sea, some in, some just across the flow. No boats on it when I saw it, so not sure how fast it was going.
the waves were moving at about 10 ft per second, I guess.
That was in 1972...
