Moving from trees to earth! Wow! Now I have an even more passion to visit Australia! I was told the oldest exposed rock was in Scottland! I am definitely now going to visit both countries to see the absolute beauty!

Most interesting to me is the rock formations still stable after so much time. With volcanos, plate technonics, earthquakes, and people there are a whole host of ways to destroy and reform rock.
