It’s a red dawn. Particles of sand from North Africa have mixed with snow in Eastern Europe to turn a ski resort near Sochi, Russia, into a surreal Mars-scape. The red and orange snow is the result of storm clouds catching Saharan sand in the atmosphere. Last year, U.K. skies took on a reddish hue after Hurricane Ophelia brought in atmospheric dirt. Satellite images from NASA show desert dust drifting from the Sahara across the Mediterranean, and its colorful effects have also been seen in Bulgaria, Romania and Ukraine this week.
