Cerro Blanco, Peru: Dune Skiing

Not sure if this belongs in the Woodstove or Summer forum. Great pix and report from the French-Canadian site Zoneski of sand dune skiing at Cerro Blanco, Peru (I ran it through Google Translate). He mentions an almost 4,000 vertical-foot drop -- not sure if that's the total hike or what they actually skied. Regardless, pretty impressive.
