Description: Cerro Aucanquilcha, Chile, is one of those places where hell sometimes releases its surplus building material through a volcano. So huge is that deposit of sulfur, that it was deemed worth to tap, even if the stuff has to be brought down from 6000m altitude with the highest arial ropeway to a sulfuric acid plant (deemed for copper processing at Chuquicamata, see mining branch). The workers drove and walked up to the mine on the highest road that leads up to 6100 m above sea level. On this KMZs particular snapshot view looking south you can see the road approching the mountain from the left (East) reaching a snow covered plateau a bit right from the center of the view. The ropeway and one branch of the road go up the snow covered slope (you can see some of the zig-zags). The place marker sits on the mine. Since the mine ceased operation the road is open for public, though partially blocked by a landslide. And yes, there have been mountain bike traces.
