Lone Star Fire Wildfire
News – 8/30/2020

Acres: 960 
Total Personnel:
Cause: Lightning

Warmer temperatures and gusty winds associated with an approaching cold front led to increased activity on the Lone Star Fire Saturday. The fire crept into unburned pockets along the fire's edge throughout the day. There are also a number of isolated heat sources outside of the fire’s perimeter. An infrared flight last night confirmed the fire has grown over the last several days to 960 acres. A progression map is available on the fire’s Inciweb site.

Two additional engines arrived on Saturday to support firefighters strengthening protection around key Old Faithful infrastructure. Crews finished the first phase of chipping at the water treatment plant and continued cutting timber around the cell tower. Work will continue on Sunday near an aboveground power line, substation, and park cabins. A park resource team finished an archeological survey in the Old Faithful developed area and will now focus on mapping sensitive riparian habitat and rare plants. This information will help the incident management team minimize impacts to these important natural resources.

Sunday is expected to be cooler and calmer with light winds. Colder temperatures and precipitation are expected to pass through the area on Monday before warmer and drier conditions return midweek. A brief article posted on the fire’s Inciweb site explains how influential weather can be on fire behavior.

What’s Closed:

Fire activity in the western United States has created smoky conditions throughout the region. 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.
