MANAGEMENT STRATEGIES: Tactics for the next 24 hours include using aviation assets (Type 1 and Type 2 helicopters) to drop water on aspects of the fire in order to minimize further impacts to road and power line corridors.
In anticipation of wind shift back to typical prevailing directions (SSW), firefighters have implemented additional structure protection in the Lake area utilizing irrigation systems.
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.
