Genuine Ocean Whirlpool

Don't know if anyone has posted this before. I ran into a link to it while on a NE Coast Sea Kayaking board. Apparently it s the world's biggest or at least teh Western Hemisphere's biggest. The pictures under the heading 'Some "Old Sow Piglets"' look particularly scary.
Makes the tidal races in the Gate seem tiny. 28-foot tidal range is huge.

Another place this happens is Deception Pass up near Anacortes, WA.  The current rips so fast through such a narrow pass that during the right tidal movement can create whirlpools at least four feet deeper than the water and about 12 feet in diameter.  I used to work as an observer for WDFW up there in the San Juans and we used to use a launch near there and we'd really have to watch for them because the whirlpools would throw our boat sideways. Scary stuff.
