YELLOWSTONE NATIONAL PARK — The Lone Star Fire in Yellowstone National Park is still active and continues to burn despite two days of colder, wetter weather, park officials say.

The lightning-caused fire is now at 3,346 acres and park visitors are urged to use caution if smoke is present from the fire on the Grand Loop Road between Old Faithful and West Thumb.

The road is currently open but may be closed at any time due to smoke and low visibility.

Firefighters will continue to cut trees and heavy vegetation around the Old Faithful area to protect power lines, historic buildings and communication equipment.

  • Fire activity in the western United States has created a high demand for firefighting resources. The nation is currently in Preparedness Level 5 (PL5). This represents the highest level of fire activity and demand for resources.
  • All residents and visitors can assist fire efforts by following fire restrictions to reduce the potential of additional starts. Fire danger in the Yellowstone area remains very high; campfires in the backcountry are not allowed.
