Skiiers in Eastern Europe were treated to eerie Mars-like slopes over the weekend. Mountains and ski resorts in Russia, Ukraine, Bulgaria, and Romania were coated with a mysterious dirty orange snow.
The specifics of how this happened aren't entirely clear. However, many suggest the snow, which varied between yellow, orange, and brown, was the result of sand and pollen. The dirty snow was likely the result of storms in North Africa carrying sand at high altitudes.
"There has been a lot of lifted sand or dust originating from North Africa and the Sahara, from sandstorms which have formed in the desert," Steven Keates of the Met Office told the Independent. "As the sand gets lifted to the upper levels of the atmosphere, it gets distributed elsewhere. Looking at satellite imagery from NASA, it shows a lot of sand and dust in the atmosphere drifting across the Mediterranean."
