Wow -- look at this morning smoke plume -- stretching from California to Montana:
A plume from several fires...it seems to start from the Rim fire, but when it reaches southern Idaho it's definitely added to by the Elk, Pony, and Beaver Creek complex fires...and others. Or maybe a lot of it is from southern ID, spreading south into NV...? (InciWeb)
I call it a "morning smoke plume" because, as a frequent follower of my favorite satellite view, I've noticed how more-visible wildfire smoke plumes become in the early morning. I think it's because, overnight, winds die down and so the smoke is less-dispersed and so less-diluted and so more-visible, generally spreading and settling into basins. Less-dispersed, but even the light winds of night time disperse it a long way.
