On the top of the mountain, the wind is howling in the old installation of the ski station of Chacaltaya, Bolivia. The station was the highest in the world, and stops a few years ago, because of the smelting of the ice (du to global warming).
The teleski cable and tube is still there and the wind sing in it! :-)
