To stand in Deep Gorge, surrounded by deep red boulders etched with the world’s largest and most important collection of petroglyphs (Aboriginal rock carvings) dating back half to one million years, is breathtaking. It’s a quick-fire way to make you feel insignificant in the big picture. To turn 180 degrees and be confronted by millions of tons of metal structured into a huge industrial plant just a few hundred metres away is heartbreaking.
