7:  Tidal Rocks

Rock reflections in Tidal River, Wilson's Prom.

Reflections of rocks at the side of Tidal River, Wilson's Promontory, taken at low tide. The river is tidal, hence the name, and at high tide the water covers the sand on the opposite bank completely.
The orange colour on the rocks is lichen, and the dark water is caused by tannins leaching from 'Coastal Tea Tree', which is quite prolific along the Australian coastline.
