From the Superior National Forest - Updated May 29, originally posted May 25, 2026


May 29 update: 

The Superior National Forest will be completing ignitions for the remaining 25 acres today on the Sunfish Lake Prescribed Fire, Friday, May 29, 2026, on the Gunflint Ranger District. The Sunfish unit (775 acres) is located on the southeast shore of Greenwood Lake, 20 miles north of Grand Marais, MN and 3 miles south of the Boundary Waters Canoe Area Wilderness (BWCAW).

Objectives for the fire are to reduce hazardous fuels and create defensible space from wildfire around lake properties and other important landscape values; improve moose habitat and restore the ecological process of fire on the landscape. Prescribed fire treatments create a patchwork or mosaic of fire-resistant forest stands in the landscape that can reduce the intensity of future wildfires or chance of new fire starts.

Aircraft will be used for aerial ignition and firefighters on the ground will be in place on holding lines. Smoke from this prescribed fire will be visible from many locations including the Gunflint Trail, East Bearskin Lake, Clearwater Lake, Pine Lake, North and South Fowl Lakes. Smoke is expected to drift to the northeast and may directly impact the Greenwood Lake, Esther Lake, Devilfish Lake, and McFarland Lake areas.

 

A Temporary Flight Restriction (TFR) FDC 6/3663 has been put in place over this prescribed fire unit for May 28 and 29 for the safety of all pilots and aircraft. Several Fire aircraft will be working over the fire. Please do not fly in this area, including not using drones. If you fly, we can’t.



May 28 update: 

Officials from the Gunflint Ranger District-Superior National Forest plan to begin the prescribed burn in the Sunfish Lake Prescribed Fire on May 28. See more details below. 

May 27 update: 

The Superior National Forest delayed the prescribed burn on the Tail unit, scheduled to begin May 26, to May 27 due to unfavorable conditions. Officials said that conditions on the 27th are much more favorable. 

Fire staff is still looking at weather conditions to plan the remaining burns.

The Superior National Forest plans to continue spring prescribed fire operations. Fire managers expect to implement the Kawishiwi Lakes unit and on the Tail, Shack, and Elixir units on May 26, followed by the Sunfish prescribed fire planned on May 28 or 29, depending on conditions.

Prescribed fires can only occur when vegetation, temperature, humidity, and wind fall within the prescribed fire’s specific requirements.

Kawishiwi Lake Units

  • Located within the Kawishiwi Lake Roadless Area off the Sawbill Trail (Tofte Ranger District)
  • Total 1,911 acres across two units
  • Objectives: reduce hazardous fuels, reduce brush to invigorate tree growth, create mosaics of young and old forest, and improve moose habitat

Sunfish Unit

  • 775 acres, located south of Greenwood Lake off the Gunflint Trail (Gunflint Ranger District)
  • Includes both National Forest System lands and Minnesota Department of Natural Resources land
  • Objectives: reduce hazardous fuels and create defensible space from wildfire around lake properties and other important landscape values; improve moose habitat, and reintroduce fire to the landscape

Tail Unit

  • 465 acres located about 15 miles up the Sawbill Trail north of Tofte, MN.
  • Objectives: Reduce hazardous fuels, improve growing conditions for conifer pines, reduce slash, prepare the seedbed for seeding and regeneration, reduce balsam fir and restore fire to a fire-adapted ecosystem.

Shack and Elixir Units

  • Four Shack units plus the Elixir unit, totaling 142 on the Wanless Road, about eight miles east of Isabella, MN.
  • Objectives: Burn post-harvest slash in pine conifer stands and reintroduce fire to reduce the risk of high-intensity wildfires.


Fact sheets, maps, and a Q&A document will be posted to forest’s  Inciweb prescribed fire page. Facts sheets and the Q&A are posted on the Announcements page.

Safety, Closures, and Smoke

Public and firefighter safety remain the top priority. No recreation or road closures are expected. During active burning:
  • Travelers may see smoke or flames in the units
  • Roadways will be posted with signs
  • Smoke may settle in low areas during evening hours
  • Visitors should use caution around dead or burned trees  

Why use prescribed burning?

Prescribed fires are wildland fires originating from a planned ignition in accordance with applicable laws, policies, and regulations to meet specific objectives:
  • Protect communities and infrastructure by reducing hazardous fuels and the risk of high intensity wildfires
  • Improve habitat for species such as kestrel, woodcock, moose, white tail deer, black bear, meadow vole and the rare Nabokov blue butterfly
  • Limit invasive plant species and support native ecosystems
  • Promote growth of trees, plants, wildflowers, and blueberries
  • Support indigenous Tribes’ long-standing cultural practice of fire use to maintain the boreal forest’s natural fire cycle

Drone

For safety of our pilots and firefighters, drones are prohibited near or over any fire area. in fire areas. When you fly, we can’t.
