FRASER, Colo. -- A wildfire burning south of Fraser, in Grand County, has burned an estimated 300 acres and remained uncontained.

However, the fire appeared to be holding, and did not appear to be threatening any homes or structures, said Nowell Curran, with the Grand County Office of Emergency Management.

"The fire is staying in one place and weather will determine if evacuations are necessary," Curran said.

Fire crews were pulled off the fire lines at dark as a safety measure, but will be monitoring the flames throughout the night.

Temperatures remained cool and there was no wind, said 7NEWS Reporter Jaclyn Allen, reporting from the scene.

The fire, dubbed the Church's Park Fire, is burning on the north side of Sheep Mountain near Church's Park, Curran said.

Every fire department in the county, as well as three heavy air tankers and two helicopters, are battling the blaze.

The Grand County Sheriff’s Office said it has issued emergency phone notifications for three areas, including the Young Life area, the east side of Sheep Mountain and from Church's Park to the town of Fraser. Those who received the call were told to prepare for a possible evacuation.

Officials said a temporary shelter has been set up at Fraser Elementary School.

Rachel Hoyhtya, with the East Grand Fire Protection District, said calls about the fire came in around 1 p.m. Sunday.

Earlier in the day, the fire was moving up the steep, sparsely populated mountain, away from a nearby resort.

AirTracker 7 reported that the nearest structure visible through the smoke appeared to be 15 miles to the southeast.

The East Grand Fire Department, U.S. Forest Service District 8, and the fire departments of Granby, Grand Lake and Hot Sulphur Springs responded to the fire along with the National and State Forest Service.

Incident command has been turned over to the Forest Service, since it is burning on public land operated by the Forest Service, Curran said.

Witnesses in Fraser said they could see flames from their homes.

The cause of the fire was under investigation.

Grand County has not been under a fire ban.

Conditions are dry and there has been no significant rain in the area for two months, said 7NEWS Chief Meteorologist Mike Nelson. The land has also been plagued by pine bark beetle kill, which may have contributed to the fire's rapid growth, firefighters said.

County Road 50 west of Hwy 40 is closed.

Firefighters will remain on the scene throughout the night, keeping an eye on the fire and making sure it doesn't spread.

Meanwhile, some residents are packing their bags, just in case.

"We're just taking everything out -- my china, my grandmother's sterling silver," said Cyndy Flores, who got the reverse 911 call to be prepared to evacuate. "We're going to stick it out for the night keeping our fingers crossed, but we're ready to go if we need to."
