The fire burned up to and around the cabin but firefighters arrived in time to extinguish the flames before they ignited the cabin. The northwest corner of the allotment was impacted by the fire but the cabin survived intact, said acting Tok Fire Management Officer Kato Howard.
“They had to go in there and beat out some flames but the cabin’s still there,” Howard said.
The Black Hills Fire is located in Limited protection area within the Tetlin National Wildilfe Refuge approximately 56 miles southeast of Tok. The lightning-caused fire was reported Wednesday afternoon and the initial size up put the fire at around 60 acres. Because it plotted in a Limited protection area, no suppression action was taken to allow the fire to function in its natural ecological role. Fire managers focused on protecting the cabin and allotment, as specified in the Alaska Interagency Wildland Fire Management Plan.
Fanned by erratic winds caused by passing thunderstorm cells and recent hot weather that has dried out fuels, the Black Hills Fire blew up quickly on Thursday afternoon, growing to an estimated 2,500 acres by 3:30 p.m.
A helicopter shuttled part of the Tanana Chiefs Crew into the fire to begin setting up protection measures around the allotment and cabin. The crew began cutting a saw line around cabin but had to retreat to a safety zone in a burned area due to increased fire intensity. Pushed by gusty winds, the fire made several erratic runs away from and toward firefighters working to protect the allotment, Howard said. Once fire intensity lessened, the crew was able to reengage and protect the cabin.
“Yesterday was a bit of a hectic day,” he wrote in an email.
Two water-scooping aircraft based at Fort Wainwright and two helicopters made multiple water drops on the northwest corner of the fire closest to the cabin and an air tanker made multiple retardant drops around the cabin and allotment. There were seven fixed- and rotor-winged aircraft working over the fire late into the evening.
It’s unclear how much of the allotment was impacted by the fire and the 3,500-acre estimate is rough guess because smoke and weather limited visibility for aircraft, Howard said. Fire managers should have a clearer picture by this afternoon as to how much of the allotment burned.
The remainder of the TCC crew was shuttled into the fire Friday and the crew is working to mop up areas burned around the cabin and allotment and to cut saw lines around both. They will lay a hose line around the allotment and cabin to plumb it with pumps and sprinklers that can be used to wet down the area around both if the fire threatens them again.
The fire received moderate to heavy precipitation overnight Thursday to help reduce fire behavior and light precipitation was falling on and off today.
A Temporary Flight Restriction (TFR) has been put in place over the fire area to ensure a safe environment for aircraft working on the incident. Go to https://tfr.faa.gov/tfr2/list.html for more information on the TFR.
