9/24/21 - The area closure is lifted; some road closures remain in place

West Lolo Complex (Thorne Creek) Wildfire
Closures – 9/24/2021

Due to recent cool weather and precipitation, fire managers will lift the area closure for the Thorne Creek Fire on September 24, 2021. All roads and trails within the burned area will be open unless otherwise specified below. The Thorne Creek Fire is 81% contained and 19 personnel continue to work on suppression activities. Currently, all mechanical suppression repair is complete on the fire. Firefighters continue mop-up activities and are working to identify and remove hazard trees along the main Thompson River Road and the West Fork of the Thompson River Road. Interior smoking/burning of heavy fuels may continue to occur within the fire perimeter on warm, dry, and breezy days or until a season-ending event occurs, like significant snowfall.

After hazards along roadways are addressed, crews will work on removing/falling immediate hazard trees along major trails. Trail clearing and hazard tree removal in this area will be an ongoing process and will take multiple seasons to address, especially after winter weather impacts the burned area. 


 NEW! (9/24/21) The area closure has lifted, some road closures remain in place: 

  • Thompson River Road (#56) closure will remain in place from the end of the pavement, just past Copper King Campground, to Barktable Road (#16271) with barriers at each end.
  • Due to the Thompson River road closure, Clark Memorial Campground remains closed.
  • Due to the Thompson River road closure, access to the Pricilla/Sundance Ridge (#433) trailhead off the Thompson River Road remains closed.
  • The West Fork of Thompson River Road (#603) will remain closed which means access to the trailheads along the West Fork of Thompson River Road will be closed including: Honeymoon Creek Trailhead (#469), Big Spruce Creek Trailhead (#1102) Cabin Lake/Four Lakes Loop Trailhead (#450/460/459) and Goat Lakes Trailhead (#478). Access to these trails is still available by foot via trailheads located off the Graves Creek Road or north of Thompson Falls.
  • The lower/southern portion of Graves Creek Road is OPEN; however, the upper Graves Creek bridge was burned in the fire and Vermillion Pass is inaccessible from Thompson Falls. The District is working on plans to replace the burned bridge.
  • Access to Winnimuck (#506), Vermillion/Headley (#528), and Slide Rock (#529) trails will only be possible via roads following the Vermillion River and/or Willow creek on the Kootenai NF to the north.
