it to burn/smolder itself out. Bog fires burn peat underground. They can smolder all winter and come back to start more fires next Spring. Rainfall helps, but won't solve this. It's not unlike having an oil field fire.
You need to dig trenches to contain. Lots of them. The Canadians haven't done enough so far...other than restrict people's rights and claim global warming.
Now the human factor of the fire start is very possible....as is our old enemy China who was allowed into that country foolishly. China was recently caught trying to sneak crop pathogens into Michigan which could massively hurt our food supply. This sort of act is not beyond them....but that is just conjecture at this point.
But I'd be a LOT more concerned about them than the simple day hikers.
(This is totally different from the Cali fires that Trump was referring to where Cali stupidly refused to clear old dead, dried timber while also having massive increased population....he was correct in that case).
