Probable Start Date: September 13, 2009
Reported: September 23, 2009 Cause: Lightning
IMPACTS TO VISITORS AND AREA RESIDENTS: The road is currently closed from south of the Lake developed area to the West Thumb Junction due to fire actively burning along 1.5 miles of the road, and an undetermined number of hazardous snags falling across the road(SEE MAP). Access is available from the north and east to the Lake developed area (Lake Hotel and Lake Lodge); and to the Old Faithful area from the south and west.
Snag removal will take place when conditions are safe for firefighters. The road will remain closed throughout today and tonight. An assessment of when the road might reopen will be made when it is safe to do so.
As a reminder, the road between Norris and Madison is also closed due to road construction (SEE ABOVE 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.
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.
No facilities have closed at this time due to fire activity with the exception of the launching of private water craft from the Bridge Bay Marina. Water craft can still be launched from Grant Village.

Firefighters have implemented structure protection in the Lake area utilizing irrigation systems 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.
