In Montana you are financially responsible for all losses incurred due to a fire you start. Of course nobody is required to prove billions in insurance coverage before lighting up their yarn brush pile... Fires larger than 48" diameter are generally banned in the dry season here, although that's plenty big enough to set a forest on fire. Sometimes local and federal agencies (depending on jurisdiction) ban all open fires for a while during very dry/windy conditions, and when there's already a big fire to avoid their resource becoming stretched.
