seemed to go on forever, an ev- er-changing landscape of the old and the new formations, as the prevailing winds from the Tanami desert shape the sandstone domes. The bands created by differing layers of stone; the dark layers hold more moisture allowing an algae (cyanobacteria) to grow, the orange bands are those that contain more iron and manganese. The moisture that seeps into the stones often freezes at night, this is a tropical region on the edge of a desert yet at night the temperatures drop, the frozen water expands and creates cracks opening the stone to the forces of erosion; water and wind. It’s a spectacular sight made more impressive by the various gorges, channels and cracks in the earth. Impact craters are visible, one so large it is seven kilometres across, the impression in the earth looking like a giant cow pat, perhaps ironic given this land was once cattle coun- try before its ‘discovery’.
