The Wallow Fire in the White Mountains was started by two idiots who were camping and didn't put out their fire.

But when they were returning to their campsite several hours later, the Malboeufs told investigators, they could smell and see smoke from the area. "They tried to return to camp to cut their dogs loose, which they had left tied up in camp, but could not get close because of the fire and smoke," the complaint stated.
I repeat, idiots. Can't blame this one on the Forest Disservice, or border crossers for that matter.
After decades of overly aggressive fire suppression policy, the Forest Service doesn't have a lot to work with. Even if they turn around and do controlled thinning and burns and never screw up, there will be large devastating wildfires. IMO the effect of climate change will be visible over long timespans (not one year to the next) as the vegetation that returns is not necessarily going to be the same as what was there before.
