Omigosh, clear skies in western Montana - I almost don't know how to process this!
Weekend winds cleared the air in the Missoula valley to astonishing clean, but the view toward Lolo, Montana, (centre of photo) still shows thick smoke fug lingering further south.
After so many weeks, the clear air was almost unbelievably bewildering, even while we were thankful to breathe deep and get active outside.
(Sadly, pessimism lurks with thoughts of "Better enjoy it while it lasts!")
