On the way from Wilpena pound to Marree we drove for an hour through the Brachena gorge, it was 15km long and took almost an hour to get through. There were lots of different coloured rocks. We saw lots of different rock formations that have built up over 600 million years. They have been pushed up out of the ground. We hit our first water crossing. The water was up to the top of the tyres nearly.
