About 230 fire personnel are managing the Arnica Fire in Yellowstone National Park for multiple resource objectives. They are allowing the burn to progress naturally in lodgepole forest areas where ecological benefits can be achieved, while using helicopters to cool portions of the fire perimeter nearest areas that are more at risk.
Structure protection measures, such as clearing brush around buildings and setting up sprinkler systems, are in progress at Bridge Bay and Lake Village. Park visitors are reminded that the Lake Village area, including the Hotel and Lodge, remains open and is accessible from the North, Northeast, and East entrances.
Natural Bridge Trail and Elephant Back Trail are closed to the public due to unsafe fire conditions. The Grand Loop Road between Fishing Bridge Junction and West Thumb Junction is closed indefinitely because of active fire and falling burned trees. Firefighters will assess the area and remove hazardous trees when it is safe to do so.
The fire started by lightning around September 13th and was discovered last week. Officials estimate the fire will be contained by the end of October.
