Individuals with weakened immune systems and those with heart and lung conditions could be most affected.
Smoke and flames can be seen from the Grand Loop Road. Drivers are advised to use caution and drive slowly as smoke could reduce visibility.

Yellowstone National Park is a fire-adapted ecosystem. Fire plays an important role in maintaining the health of the area’s wildlife and vegetation. Most fires occurring in the Greater Yellowstone Area are caused by lightning. Firefighters continue to monitor the Arnica Fire by air, from the ground, and from the Mt. Washburn Fire Lookout. The fire is being managed in order to protect people and property, allow natural processes to occur, and effectively use available firefighting resources.
