The giant fire started by lightning on July 31 in a remote area north of Grand Junction quickly got out of control and has since grown to the largest wildfire in Colorado history as it races through grass, sage, pinyon-juniper and fir. The combination of drought, dry vegetation, unseasonably hot weather and steep terrain led to several weeks of explosive growth. In one night, the fire grew by 30,000 acres. As of Friday, it was estimated at just more than 139,000 acres, surpassing the 138,114-acre Hayman fire in 2002 as the state’s largest.

Despite its massive size, only one abandoned building has burned and no injuries have been reported.

Crews will continue to watch hot spots and control the fire’s spread Monday, which only grew one acre overnight.

A red flag warning was issued Monday cautioning firefighters about the the likelihood of dry and windy weather. Gusts could reach up to 30 mph and humidity will remain low. Evening thunderstorms could brings flash-flooding and temperatures are expected to stay in the 80s.

Firefighters expect to reach full containment by Oct. 15.

Grizzly Creek fire

Acres/Location: 32,464 acres/Glenwood Canyon

Containment: 73%

Started: Aug. 10, human caused

Firefighters: 626

The Grizzly Creek fire erupted outside of Glenwood Springs and surrounded Interstate 70 between Gypsum and Glenwood Springs consuming a mix of oak brush, conifer and Aspens. Because of the fire’s proximity to the highway it has often been the state’s top priority in firefights this month.

Monday’s weather outlook is not necessarily a positive factor as dry conditions and winds up to 40 mph threaten firefighting efforts.

“If we get any spotting or flare ups, we’ll have personnel in the appropriate places to take action,” according to the Operations Planning Section Chief Karen Scholl with the Alaska Incident Management Team. “We have safety zones for firefighters identified if we need them.”

Interstate 70 drivers should expect sporadic delays as crews repair power lines and drivers should be aware of hazardous weather forecasts that include flash floods in the case of strong rains.

Officials predicted the fire would be fully contained by Sept. 18 but expended the date to Oct. 18.

Williams Fork fire

Acres/Location: 12,097 acres/seven miles southwest of Fraser in the Arapaho and Roosevelt National Forests

Containment: 10%

Started: Aug. 14, human caused

Firefighters: 361

The Williams Fork fire is burning on the Arapaho and Roosevelt National Forests and Pawnee National Grassland seven miles southwest of Fraser. The human-caused fire started near the Henderson Mill Aug. 14 and quickly grew due to high winds and steep slopes. Local firefighters immediately responded, but hot, dry and windy conditions allowed the fire to race through the timbered crowns of the lodgepole pine, fir and aspen forest.

Cold weather Monday is expected to bring rain, lower temperatures, and wind with gusts up to 45 mph. 

The fire is not expected to threaten Fraser, Tabernash and Winter Park. Some residents’ pre-evacuation orders were lifted Sunday and others were lifted Friday.

The fire is not expected to be fully contained until Oct. 31.

Cameron Peak fire

Acres/Location: 23,022 acres/West of Fort Collins, Arapaho and Roosevelt National Forests

Containment: zero percent

Started: Aug. 13, unknown cause

Firefighters: 893

The Cameron Peak fire ignited on Aug. 13 on the Arapaho and Roosevelt National Forests near Cameron Pass and Chambers Lake. It is burning in heavy timber stands over rugged terrain. Hot, dry, windy weather, combined with critically dry fuels have kept firefighters from slowing its spread.

Response to the fire grew by more than 100 people over the weekend with a total of 893 firefighters.

Crews are working to construct containment lines as well as protecting structures.

Cooler weather with wind gusts up to 35 mph are expected Monday.

East Fork fire

Acres/location: 1,680 acres/11 miles southeast of Trinidad

Containment: 15%

Started: Aug. 22, lightning

Firefighters: 95

The fire is burning on two state wildlife areas near the New Mexico border: James M. John State Wildlife Area and Lake Dorothey State Wildlife Area. Winds pushed the fire to the south toward the Colorado/New Mexico border, resulting in the evacuation of Sugarite Canyon State Park in New Mexico. The park is located on the Colorado–New Mexico state line 6 miles northeast of Raton, N.M. Although the fire remains in Colorado, a watershed near Raton is threatened and has seen some impact above Lake Dorothy.

The fire’s response teams nearly doubled over the weekend to 95 total firefighters.

Crews are working to create containment lines along natural barriers. Teams are using air support to attack the fire, including the use of two large air tankers and two Blackhawks from the Colorado National Guard.

Lake Dorothy is closed as helicopters use the lake to carry water to the fire.
