Very common thing in my country. A few weeks ago a homeless person under a bridge in my locale set up a camp fire that got out of control it burnt mostly all the vegetation and charred some of the trees in a forest area. The fire department was monitoring and set there own fires to control it. It went on for about a week and the area was very smokey and smelley. It's amazing cause the area looks mostly the same prior to the fire now except for the charred trees. All vegetation is back and green..
Oh, that is unfortunate. The smell of burnt things and also trees stays for some time. When I drive to one of my gigs, there is an area of forest that suffered a forest fire some months ago. All black trees now, and it seems that the cause was a heater from one house.
