Fires blazed in northwest Colorado Friday night amid low humidity and gusty winds.

Dry thunderstorms and lightning sparked three fires on Bureau of Land Management land in Moffat and Rio Blanco counties, according to a release issued by the Northwest Colorado Fire Management Unit.

The Wolf fire, located about 5 miles south of Elk Springs, is at an estimated 700 acres and "is burning actively in sagebrush and pinon and juniper trees," the release said.

Spokeswoman Lynn Barclay said the fire was reported at 12:16 p.m. Friday. Winds up to 35 mph drove the fire throughout the day.

One 20-person hand crew and two engines are on scene with three additional hand crews and engines ordered. No containment has been reported. The fire currently does not threaten any structures, but oil and gas facilities are located about 3 miles south of the blaze.

A Type 2 incident management team will assume management of the fire Saturday.

Five miles south, the Divide fire has burned 150 acres of land. The fire was reported at 1:28 p.m.

Eight smokejumpers and one engine are currently working at the fire with three engines and one 20-person hand crew ordered.

"The smokejumpers reported high winds in the area causing the fire to make runs through the sagebrush and pinon and juniper trees in the area," the release said.

There has been no containment, but no structures are threatened.

Barclay said the Piceance Creek fire started Thursday at around 7:20 p.m. and burned about 20 miles southwest of Meeker. Barclay said the fire was fully contained at 15 acres by Friday night.

Three miles east of Hayden, a 40-acre wildland fire on private land was reported around 2:30 p.m.

Bryan Rickman, fire chief with the West Routt Fire Protection District, said the fire was out by 5:30 p.m. He said the fire got close to a few power poles, but it didn't cause any damage.

Seven engines responded to the fire. Rickman said the cause is still under investigation.

"It's terribly dry," he said.

Two other small wildland fires were reported Friday afternoon in Rio Blanco County but have been contained.

The National Weather Service had issued a red flag warning for northwest Colorado through 9 p.m. Friday.
