Firefighters continue to fight a fire that has ripped through approximately 1,000 acres of juniper and sage brush west of Payson.

A wind shift caused the fire to spread Friday night at about 6 p.m., when the first crews arrived to fight the blaze. About 80 percent of the land burned is owned by the federal government, said Uinta National Forest spokeswoman Loyal Clark.Payson city owns the remaining acreage left charred by the blaze, which investigators have determined was started by humans. Clark said arson has not been ruled out.

"Investigators have not been able to tell if it was deliberate or accidental," she said.

Firefighters from Payson, Santaquin, Utah County, U.S. Forest Service, Salt Lake County and Idaho assisted in the effort.

No homes were damaged by the flames. One family was evacuated when flames swept close to their house.

"There was no damage, and that was totally amazing," Clark said. "Last night, when the fire was in full fury, there was one house that the fire burned completely around."

Forest Service officials employed 20-member firefighting crews to stamp out the fire during the night. In all, more than 200 fire fighters were called in to help.

Clark said two tankers and one helicopter dumped a total of about 10,000 gallons of water on the fire Saturday. A tanker was called Friday but could not come until daylight.

One firefighter was injured when a hot cinder landed in his eye. He was taken to Utah Valley Regional Medical Center, where he was treated and released.

Clark estimated the fire would be completely controlled by 8 p.m. Sunday.
