Devils Marbles

We chose the Devil's Marbles as a site to observe the transit. Its about 400 kilometers north of Alice Springs. There are a whole lot of round rocks piled on top of each other there which were formed when rock layers split by erosion forming square blocks then gradually had the edges eroded to form ball shapes.
