Montgomery Reef is a large coral reef approx. 100 square miles in area located just off The Kimberley coast. Huge and pristine it is an amazing place to visit. As the tide falls the huge amount of water over the reef has to fall too and creates cascades all along the edges of the reef. The tidal rise and fall can be as much as 11 metres! The dark blue in the image above is the top of the reef still covered with water and lower there is a reef heron fishing the cascade.
This reef is special too in that it lies exposed to the sun for many hours each day and yet the corals stay alive. Scientists have found that the corals extrude a type of sunscreen that protects them from bleaching in the sun. The noise from the run off of many hundreds of cascades like this is very much like being near a large waterfall and the water is just as turbulent.
