I left from Butte, Mt on wednesday afternoon, for Colorado. It was very smoky along I90 due to new fires on Homestake pass near butte and another above bozeman. I got off I90 at cardwell and headed south. The smoke began to thin out at ennis.
I drove through island park, ashton, and driggs, Id. It was pretty clear. Only a very slight haze. Much better than it was two weeks ago. So the Yellowstone area is good. You can see the tetons again.
I shot this pic tuesday night. The smoke on the mountain is the beginning of the homestake pass fire
