Montgomery Reef from........

.........another helicopter :))
This is another amazing phenomenon with the reef becoming exposed at low tide and then, at high tide, 180 square kilometres of reef is totally under water. These "streams" we see from the air flow continuously as the equilibrium between the high and low tides is never attained.

My extra is another local. I was blown away by the sight of this enormous sea eagle standing on the edge of the reef looking at the water. On closer inspection we realised there was a feeding frenzy of black tipped reef sharks right in front of it!  The image is not too good because a) moving boat, b) wrong lens (don't you hate that!) c) it was far, far away ;)
Maybe look in LARGE and you may see what I saw
