Wildland fire in the canyon
A 100 acre wildland fire extending from just south of the Riverhouse Grill past the intersection of Highways 64 and 191 is being called the Porcupine Wildfire. Now being managed under unified command by the United States Forest Service (USFS) and Big Sky Fire Department, crews from Yellowstone Club Fire Department and the Montana Department of Natural Resources and Conservation are also on the scene. The Gallatin County Sheriff’s Office has given evacuation notices to owners of a number of structures near the fire perimeter shortly before a public safety alert was issued stating the fire was “just south of Big Sky, spreading north rapidly and is now across Ophir School.” Structure protection efforts are underway.
A prescribed burn for aspen restoration was underway by the USFS.
“We do think it is connected to the Porcupine Prescribed Burn, but it is over a mile away, so we are not sure,” said Marna Daley, Custer Gallatin National Forests Public Affairs Officer. “It certainly appears that the two are connected just because of the timing, but the distance gives a different story. We will have [a fire investigator] look into that to see if they truly are connected.”
Daley noted that fire progression has seemed to stop. “[It has] burned into a rocky hillside, not actively progressing at any rate at the moment,” she said.
This is a developing story.
