This waterway is a very interesting area. Not only is it breathtakingly beautiful at every turn, but this is one of only 60 areas in the world that has what is called a "tidal bore". As the old tide is still flowing out of the inlet, the next tide is trying to rush in. Eventually the new tide overcomes the old and a wall of water comes down the waterway at about 15 mph. I saw it once the last time I was in Alaska a couple of years ago. It looks like a wall of water about 2 feet high flowing steadily down the cove. I read that it could be 10-15 feet high in the spring. I missed it this trip as it happened while I was in meetings. Anyway, beautiful and very cool area.
