IMPACTS TO VISITORS AND AREA RESIDENTS: The road between the junctions at Lake Village and West Thumb remains closed indefinitely due to fire actively burning along both sides of 1.8 miles of the roadway. Numerous burned trees (snags) are falling across the road, adding to the hazardous conditions. Snag removal has begun and will continue only when conditions are safe for firefighters.
No facilities have closed at this time due to fire activity. The Lake Village area is still accessible from the North, Northeast, and East Entrances, and the Lake Hotel and Lake Lodge are open for business. The Old Faithful area is accessible from the South and West Entrances.
All entrances are open. As a reminder, the road between Norris and Madison is also closed due to road construction (SEE MAP). Visitors are encouraged to stop at park visitor centers and area chambers of commerce for assistance with trip planning in and around the park.
Smoky conditions will affect air quality in certain areas today. Individuals with weakened immune systems and those with heart and lung conditions could be most affected.
The Elephant Back and Natural Bridge Trails have been closed due to fire activity in these areas. Check at park visitor centers or backcountry offices for the current status of other hiking trails and backcountry campsites in the area.

MANAGEMENT STRATEGIES: Currently, 230 personnel have been assigned to the fire.

Firefighters have implemented protection for housing, lodges and historic buildings utilizing sprinkler systems, hose lines and fire engines.
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.
