We also have two Special Impact Zones: 1) the Missoula Valley and 2) the Seeley Lake area. Burn limits are necessary in these zones because smoke from many burns can have a huge impact on public health.
Missoula County topography creates three airsheds that can trap material such as smoke and pollution.
We all know it's best to burn outdoors when we have the best conditions for Outdoor Burning. One consideration is air quality.

Outdoor Burning Status Spring in Missoula County for Fire Danger
Western Montana valleys are known for their air inversions. That's when woodsmoke and other pollutants get trapped in the valley floors making the air unhealthy for humans to breathe. Our Online Burn Permit System helps with this. SO thank you for not burning on No Go Days.
