KANOSH, Millard County "” Fire officials plan an afternoon "burn out" today at the southern end of the Millard Flat fire, which may require another I-15 closure while crews work near the freeway.
Firefighters are hoping to establish a containment line that will keep the fire from spreading toward Mandersfield and Beaver.
The state's largest-ever wildfire has been burning since Friday. The blaze was considered 40 percent contained as of Thursday morning, up from 30 percent Tuesday and Wednesday. A total of 351,549 acres have burned so far.
The burn out is planned near the Mandersfield exit on I-15. Public information officer Vince Mazzier said the objective is to conduct a controlled burn on grasses between a man-made fire break near the freeway and the active fire burning to the northwest. Just how many acres of range land will be included in the burn out has not been determined.
