KACHINA VILLAGE, Ariz. (AP) — Hundreds of firefighters worked Thursday to hold off a wildfire that started in a scenic canyon in northern Arizona, prompting residents of outlying areas of Flagstaff to prepare to flee and blanketing the city in smoke.
The human-caused Slide Fire started Tuesday and had burned 7.5 square miles in and around Oak Creek Canyon, a scenic recreation area along a highway between Sedona and Flagstaff.
Fire incident commander Tony Sciacca said the fire was 3 to 3 1/2 miles away from the residential areas of Forest Highlands and Kachina Village, where 3,200 residents remained under pre-evacuation warnings. Firefighters had no containment on the blaze, but were pleased that it only grew a couple hundred acres overnight after increasing tenfold in size the previous day.
A primary focus of firefighting efforts will be to pinch off the fire where it has reached the top of the canyon's northeast corner to keep it from burning northward toward the residential areas, said Dick Fleishman, a spokesman for fire managers.
"This is an hour-by-hour deal," Sciacca said.
Sciacca said 500 firefighters were assigned to the fire Thursday, with an additional 200 personnel expected later in the day as more crews and engines arrive.
The weather may help, with weaker wind and slightly higher humidity expected Thursday and a chance of rain by Friday, Fleishman said.
As smoke billowed over their homes, residents threatened by the flames filled their vehicles with clothes, heirlooms, medication, legal documents and family pictures.
"I'm a Korean War veteran. There's not much that worries me," said 82-year-old Dick Summit, who decided to leave town and arranged to stay with a friend in nearby Flagstaff.
"It's pretty bad, we're all ready," said Ken Patrick, a Flagstaff city worker whose home was among those threatened by the fire.
Elsewhere in this village of about 1,400 off Interstate 17, residents were clearing brush away from their homes and hosing down the landscape. Search and rescue crews with the Coconino County Sheriff's Office were going door to door while pre-evacuation warnings were in place. For those who they knew were safe, they placed a yellow ribbon on their mailboxes.
The fire broke out at the start of the tourist season and closed the main road between Sedona and Flagstaff. It's burning near Slide Rock State Park, a popular recreation area because of its natural rock water slides.
Sophie Lwin, of Peoria, said she had relatives from the Los Angeles area coming in for a weekend at the Butterfly Garden Inn, which had to evacuate because of the fire.
"It's Memorial Day weekend. It's going to be so hard and so expensive to get anything anywhere else," Lwin said.
There were no reports so far of injuries or structures burned.
The fire forced the evacuations of 100 threatened businesses and homes in a 2-mile stretch north of the state park.
As the fire moved up the canyon's steep walls, it sent up large amounts of smoke and ash and created hazy conditions in Flagstaff, about 15 miles from the blaze.
The blaze presented several challenges for firefighters, including steep terrain, thick pine forest, gusting winds and the drought conditions, said Bill Morse, a Flagstaff Fire Department captain and a spokesman for firefighting managers.
The fire comes less than a year after a blaze in nearby Prescott killed 19 firefighters who were part of a Hotshot crew.
