hey Hellbender, 2.86 million acres burned up in 1910 in Idaho and Montana, of course your source is 12 years old so it can't be blamed for not knowing what happened in 2007, You can though.

care to know how much burned up this year in Idaho and Montana? 2.62 million acres

Also, there are areas of the 1910 fires that never regrew trees, some of the areas are grasslands, I'm kind of well versed in the 1910 fires, you'd better pick a subject you know more about like envirowhackism or something
