SUMMERHAVEN, Ariz. — The uncontrolled wildfire that destroyed more than 250 homes in this mountaintop community moved on a course Sunday that would take it into an area where terrain and lighter vegetation will make it easier to fight, fire officials said.
However, crews didn’t know how soon they would be able to attack the fire in that area, and the blaze’s growth in other forested areas was still creating difficulties.
“This fire’s going to be here for a while and it’s going to be very large,” said Jeff Whitney, deputy commander of the team battling the fire.
The fire had burned across more than 8,800 acres in the mountains northeast of Tucson and was only about 5 percent contained Sunday. Firefighters don’t expect to totally control it for a few weeks.
Nance Crosby and Robin Quillian were at the fire command center Sunday, trying to find out whether their summer cabin was still standing.
“It never occurred to me to try to get anything out,” Crosby said. “I never thought it would get this bad.”
The blaze was fueled by pine forest ravaged by years of drought and a beetle infestation and driven by wind gusting to 60 mph as it roared through Summerhaven on Thursday. The flames soon spread across the top of 9,157-foot Mount Lemmon and headed down the north slope.
Firefighters focused their efforts Sunday on an area around a University of Arizona observatory and a group of radio and television towers, and a ridge where they hoped to stop the fire before it advanced on scattered homes.
Three towers had already been lost.
Whitney said the fire had charred a half-circle around the observatory. Crews using hand-held torches burned grass and brush Sunday to try to close the circle and deprive the fire of the fuel it would need to move into the observatory complex.
Crews also planned backburns to clear vegetation along the ridge, where they were making a stand between the flames and homes southeast of Summerhaven.
In town, firefighter Paul Miller was part of a crew that went through the burned houses looking for hazardous materials such as small propane tanks that hadn’t exploded in the fire.
Trees were dry and would burn quickly if the fire came back.
“There’s still danger,” Miller said.
Whitney said officials evacuated a camp that had been scheduled to host 250 people beginning Sunday. The camp was about three miles from the fire’s northern edge.
The cause of the fire, which began Tuesday, remained under investigation. Investigators were expected to survey the fire’s starting point Monday.
The community of Summerhaven had about 100 year-round residents, but its population grows during the summer and weekends as Tucson residents drive up the mountain to escape the desert heat.
