Crews are battling a new wildfire that sparked on South Mountain in Tooele County Monday evening and grew rapidly overnight.
As of Tuesday morning, the fire was an estimated 1,000 to 2,000 acres and 0% contained, according to the North Tooele Fire District. Wind gusts up to 55 miles per hour contributed to the fire’s overnight activity, Utah Fire Info said.
The fire burned an area south of Stansbury Park and west of Tooele. Fire officials urged people to stay away from the fire and not to fly drones for footage of the blaze, as it prevents the use of air support.
