Kennecott Utah Copper was forced to halt copper production at Bingham Canyon Mine when a 165-million ton landslide (an estimated 85-92 million cubic yards) created this massive crater. The company had planned for the possibility of a landslide and was monitoring all movement within the mine, but they could not predict that it would be this big. The largest man-made excavation site in the world was largely collapsed by the largest human-caused landslide in history and lots of equipment was buried under the debris. Deseret News photographer Ravell Call got these incredible shots of the aftermath. The clean up here will be a grueling process.
