Man-made or Mother nature?

Working on the theme from my last post, I'd like to offer a challenge to everyone viewing. Which of the following two pictures is mad-made and which is the creation of Mother nature?

Respond here or on Facebook and we'll see if everyone is in-sync with their inner Earth-goddess!

I'll give the answer, and what each picture is of, in a couple of days.

Good luck!

Sand and rust

The beaches of Fraser Island, off the east coast of Australia, reflect the maritime history of the nation. 

This wreck, whose now rusted supports jut out of the sand like so many broken ribs, was a stark reminder of that history.
