 2007 Siberian orange snow

The phenomenon known as "orange snow" occurred in Siberia in 2007 when a thick layer of orange-hued snow blanketed the region. This unusual event was attributed to the presence of dust from a nearby desert, specifically the Taklamakan Desert in China, which was carried by winds and settled on the snow. The colored snow was a result of the dust containing iron oxide, which gave it the distinctive orange color.
