I once saw an interesting documentary on wildfires. It seems that by preventing natural forest fires for the last 100 years we've done a fabulous job of allowing 100 year accumulation of fuel from fallen trees to build up. We've also let a ton of undergrowth proliferate and allowed the trees to grow entirely too close. All combined, when there's a forest fire now, it's an unstoppable torrent that lays utter waste to uncountable thousands of acres. Used to just burn off the underbrush and leave most of the trees in a relatively cool fire. Now a fire leaves a parking lot.
The forests aren't nearly as passable or pleasant now either as they were 100 years ago.
Support controlled burns, it's the best solution to preventing this. But most people bitch about the smoke, so they're hard to do.
