YELLOWSTONE, WYOMING (September 16, 2020) — The Lone Star fire was mapped yesterday. Acreage increased from 3,348 to 3,914 acres due mostly to spot fires, creeping and smoldering. The fire continues to hold heat and potential for growth remains. Warm temperatures along with low relative humidity could cause the fire to become more active in the next few days. A widespread haze may be visible in the area through the end of the week as smoke from the fire mixes with smoke from West Coast fires. The Grand Loop Road between Old Faithful and West Thumb could close if smoke or fire impede the movement of traffic or the road becomes unsafe to drive.
Firefighter and public safety are always the top priority in all efforts.
Fuel reduction and structure protection continue. Fuel reduction efforts will focus on the Old Faithful residential area and other utility infrastructure. This creates a fire buffer that will continue to protect natural resources, cultural treasures, and visitors and residents well into the future.
Fire activity in the western United States has created 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. Read more about backcountry fire restrictions in the Backcountry Situation Report.
