More importantly, is the way the fires start. I wish the images went back before sept 8th, because thats when this effect was visible. The wind is blowing west, as seen via the smoke. But the OR fires spread south over the course of a day, as if an NPC were driving and starting them. Odd that so many fires independently start in the same day, despite most being too far apart to ignite each other.
Patricks image shows a major hwy, but there's plenty of smaller roads that go right through the fires.
There would be a lot more fires in the drier eastern halves of those states if they had occurred naturally.
Conclusion: the fires are arson by climate cultists to whip up fear.
