  • Smoke from the Brimstone Fire in Yellowstone National Park may be visible from Bridge Bay, Lake Village, Fishing Bridge, the East Entrance Road, and communities east of the park. 
  • Due to hot and dry weather, the Brimstone Fire grew to an estimated 80 acres the evening of August 28. See map for details. 
  • Public and firefighter safety is the first priority for park staff. This wildfire does not pose a threat to visitors. All services are open. All roads leading into and through the park are open. 
  • Park visitors and communities east of the park should anticipate varying levels of smoke from the fire. 
  • The following closures are in place. See map for details. 
    • Campsites 5E1, 5E2, 5E3, 5E4, 5E5, 5E6, 6B4
    • Thorofare Trail between 5E8 (just south of the spur trail to 5E8 campsite) and Beaverdam Creek 
    • Hikers can check the current status of the trail and campsites at Backcountry Situation Report.  
  • Due to the increased fire activity and additional closures, park staff are working hard to reroute backpackers around the impacted area. 
  • When managing a fire, park personnel also manage risk. Managers will monitor the fire and prepare long term management plans that address safety of firefighters and the public, protection of structures, and natural and cultural resources. 
  • Brimstone Fire photos are available on Flickr.
  • The Brimstone Fire was detected on the afternoon of August 26 east of Yellowstone Lake.
  • Likely caused by lightning, it is burning in a spruce and fir forest.
  • The Greater Yellowstone area is a fire-adapted ecosystem. Fire plays an important role in maintaining the health of this area's wildlife habitat and vegetation.
  • Fire danger is HIGH in Yellowstone. There are no fire restrictions currently in place in the park. Campfires are only permitted within established fire rings in campgrounds and some backcountry campsites.  
  • To date, four fires are active in the park. Stay informed about current fire activity
