CLINTS WELL, Ariz. - A fire that began Friday has burned an estimated 8,623 acres and destroyed structures in northern Arizona, fire officials say.

The fire, which started northeast of the Blue Ridge Reservoir in the Coconino National Forest, was zero percent contained as of Monday morning.

Forest officials said it's unknown how many total structures have been destroyed by the Tinder Fire, but did confirm some were homes.

Gov. Doug Ducey declared a state of emergency Monday for the Tinder Fire.

Coconino National Forest officials said significant fire growth occurred Sunday and prompted evacuations as high winds drove the fire into communities to the north and east.

Several small communities have been evacuated as a precaution because of the wildfire, which is threatening about 1,000 homes in a forested area of north-central Arizona.

Coconino County Sheriff's officials on Sunday ordered the immediate evacuation of Moquis Ranchettes, Starlight Pines, Clear Creek, Timber Ranch, Tamarron, Pine Canyon, Blue Ridge Estates, Ponderossa Pines and Mogollon Ranches.

The fire remains active in these areas and the priority now is providing for emergency responder and public safety, officials said.

Jerry Erwin, who has a summer home in Happy Jack, only had time to grab his dogs and a bag of clothes from the home.

“We had to go get the dogs and it was about 2000 yards away from my house," Erwin said. “We barely made it in."

The cause of the fire remains under investigation, but authorities say it's believed to be human-caused.

The 500 firefighters and other personnel assigned to the fire include seven hotshot crews plus engines, bulldozers and helicopters.

Erwin's hoping they'll be able to save his home.

"Hopefully it will still be there. We built it for our retirement," Erwin said. "At least we got out.

The wildfire also has resulted in closures of several forest roads.

A Red Cross shelter for evacuated residents is located at the Twin Arrows Casino at 22181 Resort Boulevard in Flagstaff.
