aze that spoils the clear views and stunning vistas we look for in our recreational areas is caused by sooty particles in the air as well as smog-forming ozone. Tons of airborne particles are produced by fires, both unplanned and planned. Managed fire is an important ally that is necessary for healthy forests. Smoke from these fires is minimized by reducing fuels and burning during the most favorable weather conditions. 

Careful predictive plans for smoke dispersal are filed and monitored. In contrast, unplanned wildfires send tons of particulates into the air every year. A large number of these catastrophic blazes are started by human mistakes like the Southern California wild fires in October-November 2003. 

Also, there are still other fires that we can collectively control, the fires in campsites, indoor fireplaces, and wood burning stoves that send smoky particles into the atmosphere, polluting the air and ruining visibility. We need to follow park regulations for burning and help clear the pristine air.

Camping:

5. When planning to have a campfire, know and follow recreational area regulations by burning only during the hours when fires are permitted.
6. Find out if firewood can be gathered or if you need to bring your own. Gather only in designated areas.
7. Avoid using firewood over four inches in diameter, because it usually doesn't burn completely. Burn only small pieces of dead wood. Don't chop vegetation off standing trees.
8. Be aware of smoke and never leave a fire unattended. Consider using other means of cooking such as propane stoves.
