Hale said they cut fire line using a tractor and cut brush using a chain saw in case the fire threatened the sister's home.

"It was moving pretty good," Hale said of the fire.

Collins said that at one point he saw a man running down the road, trying to get home. Collins said he gave him a ride but they had to drive through an area with flames on both sides of the road and the house was surrounded by flames.

4:40 p.m.: Residents evacuate with flames close behind

Terrie Smith evacuated from her home near the corner of Driftwood and Creek trail and drove down Bear Creek Road until she found some shade and cell phone service.

Smith, joined in her Subaru by her dog Bella and four cats, said she was nervous about whether her house survived the fire.

“It’ll be by the grace of God if my house is still standing,” she said.

She was working in her yard when sheriff’s deputies told her to leave. “I had no time to get anything,” she said

When she left home with her animals and suitcases she could see flames on the hillside behind her house. A neighbor said there was fire in his yard, but she wasn’t sure about how her own home fared.

She was also concerned about the two horses that she left behind. She also had indoor cats, but she left a door ajar for them so they could escape the house.

Prior to Thursday's fire, Smith said she was worried the area north of Redding would get hit by fire this summer.

“We just had a feeling, all of us out here north of Redding, because the west side (of Redding) burned up last year,” she said. “So many family and friends lost their homes.”

While Smith, who lives south of Bear Mountain Road, was evacuated ahead of the fire. Many residents living on the north side of Bear Mountain Road were allowed to remain.

Crowds of people stood alongside the road and watched the smoke plumes in the distance and the occasional air tanker drop loads of retardant ahead of the fire.

Update, 4:20 p.m.

Steven Griffith said he stayed behind to save his home on Driftwood Trail, but there were moments when it appeared he was going to lose that battle.

He said the fire jumped Bear Mountain Road in a matter of minutes and raced south up the hill toward his house.

“My son was yelling, telling me ‘We gotta go! We gotta go!’ Everything was on fire,” Griffith said, pointing and moving his arm in a circle in the air.

He stayed behind while his wife, son and grandson left and got a motel in Redding.

“I’m 71 years old. If that house goes I do too,” he said.

While Griffith’s house survived, the fire destroyed several outbuildings, a fifth-wheel trailer, bicycles, tools and other items in his yard.

Griffith said as the fire encircled his home he ran around with a rake and shovel putting out spot fires, trying to keep them from getting larger.

He said a fire crew showed up and helped save his home as well, he said

While Griffith’s home was spared, another house just down the hill from him was destroyed. Only the metal frame of a trailer and other twisted metal remained.

Classes have been cancelled and Griggs said he did not know when they would resume.

Griggs said that faculty, staff or students with questions about the evacuation can call one of three phone numbers: 530-339-3606, 530-339-3662 and 530-339-3661.

Traffic is now being stopped at Oasis Road and Akrich Street east of Interstate 5.

Meanwhile, roughly 50 students at Foothill High School in Palo Cedro need transportation after two of the schools bus routes were blocked after Route 299 was closed due to the Mountain Fire.

Foothill principal Steve Abbott says the school remains on high alert but classes have not been canceled and athletic activities are expected to continue as scheduled.

"We definitely have major concerns right now especially for the safety of the students who are in or near those burn areas," Abbott said. "The fire is about 9.5 miles from us and we don't see any smoke above our heads so the school is safe right now. We are working to make sure that those students get to their parents safely."

Some residents in the Jones Valley area had little time to evacuate.

Derek Chumney said he just got home from the dentist when he saw the fire bearing down on his home on Driftwood Trail in Jones Valley.

He did not have time to grab anything except his cats and his son, who was only wearing shorts, no shirt or shoes.

“When I pulled into the driveway I saw fire over here and fire over here and fire over there,” Chumney said.

His mother, Rhea Griffith, said she returned to the house a short time later and the building was destroyed.

“The only thing you could recognize was the partially melted swamp cooler,” Griffith said.

Chumney, Griffith, her grandson and a friend evacuated and booked a room at a hotel in Redding.

Original story: Firefighters are battling a fast-moving 50-acre blaze today that is threatening structures in the Jones Valley area northeast of Redding.

The fire, which started in the area of Bear Mountain and Dry Creek roads shortly after 11 a.m., is "rapidly spreading," firefighters at the scene reported to emergency dispatchers.

Within an hour the fire had grown to more than 50 acres, according to emergency dispatch reports.

Evacuations are underway for the following areas: Dry Creek Road, Jones Valley Road, Elk Trail East and West, Christian Way, Driftwood Trail, Highview Trail, Scotts Trail and Marty Road west of Bear Mountain Road, according to the Shasta County Sheriff's Office.

An evacuation center has been set up at the Shasta College gym off Old Oregon Trail.

More roads might be evacuated, and residents shouldn't rely on the list alone, the sheriff's office said on Facebook.

"This situation is very fluid and rapidly changing, if you do not see your road listed but feel you are in danger YOU MAY EVACUATE," the office's post reads.

Dry Creek Road is closed at Highway 299, according to Caltrans

Pushed by winds from the north, the fire quickly grew to 10 acres and started threatening structures, firefighters told dispatchers.

The California Highway Patrol traffic incident page said the fire may have spread to nearby brush and trees after a houseboat caught fire on Lake Shasta.

The plume of smoke from the fire is visible from Redding.
