Lone Star Fire Wildfire
News – 8/28/2020

Acres: 850
Total Personnel: 39
Cause: Lightning

Due to reduced smoke along the route, Yellowstone National Park reopened Grand Loop Road between Old Faithful and West Thumb Junction Thursday morning. Weather is expected to be warmer and drier today through Saturday, August 29. Dispersed smoke may occasionally be visible from Old Faithful and West Thumb.

Recent thunderstorms brought more than 0.3 inches of wetting rains to the Lone Star Fire and minimized new activity. However, the fire is still holding heat in its interior and grew by 30 acres. Precipitation and higher humidities can decrease fire activity, but the Lone Star Fire may smolder for some time. It might resume more activity when drier and warmer conditions return.

Yesterday, a crew installed a rain gauge in unburned timber near Lone Star Geyser to measure future rainfall. Firefighters will continue fuels reduction planning in the park which will strengthen current and future responses to fires in the Old Faithful area. Today, crews will use a chipper to reduce vegetation near the water treatment plant and other critical infrastructure.

What’s Open:

  • The Grand Loop Road between Old Faithful and West Thumb Junction is open but may close at any time if fire activity increases.

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.
