A brush fire erupted Thursday in Heiner Canyon on the north side of I-80 near mile marker 175. The land is privately owned and houses Ensign Ranch, but no structures were threatened, according to Summit County Fire Warden Bryce Boyer.

The fire was originally thought to be 2,000 to 3,000 acres, but when firefighters arrived, the number was amended to 200 acres.

"Usually when they give the first report, it's somebody guessing," said Utah Division of Forestry, Fire and State Lands Area Manager Mike Eriksson. " the time we got out there, it was a whole lot smaller than what people thought, which was good."

As of 11 a.m. on Friday, the fire was 60 percent contained and is expected to be fully contained sometime today.

Sixty-five firefighters responded from the North Summit County Fire Service District, South Summit County Fire Protection District and Uinta County, Wyoming. Twelve remain on scene. "They are mopping the rest of it up now," Eriksson said.
