Purple snow in Russia

In Russia about 2 weeks ago something very, very, strange happened. What happened was it snow purple!!!!!!! Yes that is right it snowed PRUPLE. Scientists think it was a dust cluster when Africa and Russia's air mixed. It would be IMPOSSIBLE to die all of the snow purple, it would take over a year. Maybe it was a dust cluster, maybe something else. Comment on what YOU think what happened. Although, it is extremely dangerous to eat, because it is full of dust. If you eat the dust in it you could get a rare disease, I am not 100% sure what it is called but i know you can get one. Here is a picture of the snow. You can't see it all the way it the picture but it is the best I could find.
