We Came From the Land teaches how areas around the Flinders Ranges were created and the origins of opal. This is a Wirangu story from near Ceduna on the west coast of South Australia as told by M. Miller and W.J. Miller.

A long long time ago, a huge meteorite hurtled towards the earth from the northward sky, and smashed into the ground near Eucla. Because it was so big, a dent appeared in the crust of the earth and the meteorite bounced high into the air and out into the Great Australian Bight where it landed with an enormous sizzling splash. It was hot from its trip through space so it gave off a great deal of steam and gas as it sank through the waves. But this was no ordinary meteorite. It fact, it was the spirit Tjugud.

In the deep water near by, the spirit woman Tjuguda lay asleep. All the noise around her woke her up and she was very angry. She bellowed and the elements roared with her. The wind blew, the rain pelted from the sky and the dust swirled.

From the joining of the two spirits, the Tjugud and Tjuguda, a man was born, but he was no ordinary man, he was of enormous proportions. He rose from the deep water of the Bight to swim through the maze of limestone caves which run through the earth and into the sea. Then, he emerged from the ground through the cave of the Nullabor.

This was the birth of the Wirangu man, a coastal dweller. Wirangu walked towards the east, taking huge steps in keeping with the stature of the man. Each time he stepped, the ground shook and a dent appeared in the earth. These would later fill with water and are the rock holes which can still be seen today. You can clearly trace the journey of this man.

When he reached Coober Pedy, he was very hungry so he found some food and then lit a fire. The fire he built was so fierce it burned with an enormous amount of heat. A lot of water from the body of the man dropped into the ground and was captured by the stones which held a lot of water anyway. The beautiful colours from the raging fire went down into these stones, changing the water into a magnificent display of color. This is the colour of the opal and can be found in the stones still.
