In late August, the smoke from the Oregon/California fires wasn't that noticeable in Colorado (maybe a little haze could be seen in the distance from the top of the nine 14ers I climbed).

When I drove back from Colorado at the beginning of September, the smoke got progressively worse through Utah along I-80. In Nevada it was very bad all the way through the state. Very limited views of the surrounding mountains and you could smell it.

But it started clearing up as I got into California and was pretty much gone by the time I hit the Bay Area.

Compared to last year, the fires this year have spared the Bay Area's skies for the most part.
