Photos taken at altitude a few weeks back showing the scale of the air pollution produced from the numerous wildfires in Utah, Nevada and California. The first three were from the outbound leg, from Salt Lake to Chicago:
The last three are from the return home, from Dallas to Salt Lake.
That last one shows how the ground vanished under a layer of smoke as the plane passed over the Wasatch/Uinta mountains (i.e. the Walls of Mordor). The mountains run north and south and provide a pretty effective block preventing lower level air pollution from being blown away.
