And this is what all the fuss was about

This is the horizontal falls. The height of the water at tide changes can be up to 3 meters different either side of the gaps in the mountains. this pic is taken from above our boat and looking at the tide coming in. The first gap which is clearly seen here is about a meter difference from one side to the other and you can clearly see the white water. The second gap in the furtherest range is the really good one. They rarely take boats through this one as it is very narrow and the turbulence creates large whirlpools that can easily upend a boat. We were lucky and got the ride of a lifetime through this gap with a 4 - 5 ft difference in water levels. 1.5 million gallons flows through the gap every minute.
