Arizona dust melting Colorado snow
Colorado has seen 9 dust storms already this year, darkening of the snowpack leading to early melting, a shortened spring ski season, and rapid, early snowmelt. Whew!
Most of the dust comes from Arizona, and it's worse this year than any in recent memory, probably due to years-long drought and higher than normal winds.
