This image is captured at 2,000 ft above the Vernon Islands, where the tidal variations of 5.8m expose extensive seabeds and variations in sand banks that contrast wonderfully with the impossibly blue water.
The Vernon Islands have a number of unique 'blue holes'. A little known feature of the Vernon Islands are its blue holes. The Vernon’s blue holes aren’t the usual marine sinkholes that open to the surface and are ringed by limestone or coral. These blue holes are surrounded by sandy banks and are only exposed at low tide, creating a massive network of lagoons surrounded by tessellated reef and horizontal waterfalls.
Local fishermen often use the blue holes as a swimming hole at low tide as the local resident crocs can't access the blue holes.
