An ore truck dumps a load of sulfur ore at Aucanquilcha volcano in northern Chile. The world's highest mine is located near the summit of 6176-m-high Volcán Aucanquilcha. A switchbacked road leads to the sulfur mines, which are located in areas of extensive hydrothermal alteration along the elongated summit ridge of the volcano.
