This photo was taken in Kangaroo Island, one of the great wilderness destinations in Australia. I'm no expert in geology, but the orange colour seen on these rocks is actually a lichen from the family Hymeneliaceae. Lichens occur as a result of a symbiotic relationship between algae and fungus, the algae provide food for the fungus through photosynthesis. Does anyone know more about the geological formation of these rocks?
Life always finds a way?! XD It's a really cool coloured lichen :)
