Visitors who signed up for a sled ride pulled by huskies in north-western Italy last weekend were in for a surprise – a ride through a desert-hued landscape. Red sand from the Sahara Desert fell on the snow-covered landscapes of the Italian Alps on Saturday, turning the winter wonderland a pale orange shade. The alpine village of Sestriere, in Piemonte region, was blanketed as were several regions of Europe over the past week. Giorgia Grangetto, a tour guide for the Husky Experience, joked that it was like giving a tour in the Sahara Desert. The European Commission’s Copernicus satellite monitoring programme said measured levels of particles smaller than 10 micrometre – called PM10s – increased in places such as Barcelona, Spain and in the French cities of Lyon and Marseille on Sunday. The cloud of fine sand blown north-wards from Algeria tinted skies red and mixed with fresh snowfall.
