Dirty Skies

Winds have been gusting from the south-southwest since midmorning - some gusts over 45 mph at TUS. When I drove down to the south side to go to the main Post Office before noon, I could see large clouds of dust blowing off the tailing piles at the copper mines to the south toward Green Valley. The densest of these were extending north to the Rincons and the east side of the Catalinas. Above two images show the dirty skies toward the Catalinas at noon, and an aerial view of the copper mines south-southwest of Tucson on the west side of I-19. I shudder to think of what all we might be breathing today!
