Fire activity in the western United States remains high and has created significant 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 is very high; campfires in the backcountry are not allowed. Read more about backcountry fire restrictions in the Backcountry Situation Report.
