Sunrise at a beach - this is blowing rocks - which is coral
Back from being out of town. The apparently famous rocks are in the right corner. Hard to see? Not so sure, BUT ANYWAY - these are formed by coral not rocks and the water gets jetted quickly through small holes in the rock formations to create a geyser like effect, thus blowing rocks.
On a more interesting note - part of the reason we have been getting such intensive sunrises here as of late is due to the sand blowing off the Sahara and getting caught in the atmosphere.
