Pats of Russia, Bulgaria, Ukraine, Romania, and Moldova was covered with orange snow this weekend. The odd hue was caused by sand blown into the atmosphere from the Sahara Desert that mixed with snow and rain. The same Saharan dust also resulted in a very orange tint to the Greek island of Crete, seen below.
