Old picture of the pit from the National Geographic...since then they have begun to fill in the pit.. Comments at the bottom of this picture: Morenci, Arizonas Largest Open Pit, Has converted a mountain into a hole in the ground. Towering 603 feet, the smelters smokestack can withstand 100-mile winds Just beyond it, liquid tailings from the concentrator settles into glaring white lakes of pulverized stone Twenty-three enormous banks terracing the copper mine for a bewildering labyrinth. Power shoves, each devouring the bench above it, take bites of five cubic yards. Electric trains, barely ant -size in this air view, remove the ore. Trucks and trains dump waste 1,000 feet down gullies, as on the left. Picture taken by Ray Manley
