Mountain town in Northern California devastated by wind-driven wildfire

A three-week-old wildfire engulfed a tiny Northern California mountain town,levelling most of its historic downtown and leavingblocks of homes in ashesas crews braced for another explosive run of flames Thursday amiddangerous weather.

The Dixie fire, swollen by bone-dry vegetation and gusts of more than 60 km/h, raged through the northern Sierra Nevada town of Greenville Wednesday.

A gas station, church, hotel,museumand bar were among the fixtures gutted in the towndating backto California's Gold Rush erawhere some wooden buildings were more than 100 years old.

The fire "burnt down our entire downtown. Our historical buildings, families' homes, small businesses, and our children's schools are completely lost," Plumas County supervisor Kevin Goss wrote on Facebook.

Plumas County Sheriff Tom Johns, a lifelong resident of Greenville, said that "well over" 100 homes were destroyed, as well as businesses.

"My heart is crushed by what has occurred there," he said.

"We lost Greenville tonight," Rep. Doug LaMalfa, who represents the area, said in an emotional Facebook video. "There's just no words."

As the fire's north and eastern sides exploded Wednesday, the Plumas County Sheriff's Office issued a warningonlineto the town's approximately 800 residents: "You are in imminent danger and you MUST leave now!"

A similar warning was issued Thursday as flames pushed toward the southeast in the direction of another tiny mountain community, Taylorsville,about 16 kilometressoutheast of Greenville.

To the northwest, crews were protecting homes in the town of Chester. Residents there were among thousands under evacuation orders or warnings in several counties.

No injuries or deaths were immediately reported.

Margaret Elysia Garcia, an artist and writer who has been in Southern California waiting out the fire, watched video of her Greenville office in flames. It's where she kept every journal she's written in since second grade and a hand edit of a novel on top of her grandfather's roll-top desk.

"We're in shock. It's not that we didn't think this could happen to us," she said. "At the same time, it took our whole town."

Firefighters had to deal with people reluctant to leave on Wednesday. Their refusals meant that firefighters spent precious time loading people into cars to ferry them out, said Jake Cagle, an incident management operations section chief.

"We have firefighters that are getting guns pulled out on them, because people don't want to evacuate," he said.

Theblaze that broke out July 14 isthe state's largest wildfire and had blackened more than 1,300 square kilometres, territory larger than the city of Los Angeles.

The cause was under investigation. But Pacific Gas & Electric has said it may have been sparked when a tree fell on one of its power lines.

The fire was near the town of Paradise, which was largely destroyed in a 2018 wildfire that became the nation's deadliest in at least a century and was blamed on PG&E equipment.

Ken Donnell left Greenville on Wednesday, thinking he'd be right back after a quick errand a few towns over, but couldn't return as the flames swept through. All he has now are the clothes on his back and his old pickup truck, he said. He's pretty sure his office and house, with a bag he had prepared for evacuation, aregone.

Donnell remembered helping victims of 2018's devastating Camp Fire, in which about 100 friends lost their homes.

"Now I have a thousand friends lose their home in a day," he said.

'We did everything we could'

By Thursday,the Dixie fire had become the sixth-largest fire in state history, the California Department of Forestry and Fire Protection said. Four of the state's other five largest wildfires were all in 2020.

The fire forcedLassen Volcanic National Park to close to visitors.

Dozens of homes had already burned before the flames made a new run on Wednesday.The U.S. Forest Service said initial reports show that firefighters saved about a quarter of the structures in Greenville.

"We did everything we could," fire spokespersonMitch Matlow said. "Sometimes it's just not enough."

About 160 kilometres south, officials said between 35 and 40 homes and other structures burned in the fast-moving River fire that broke out Wednesday near Colfax, a town of about 2,000. Within hours, it ripped through nearly 10 square kilometresof dry brush and trees. There was no containment and about 6,000 people were under evacuation orders across Placer and Nevada counties, according to the California Department of Forestry and Fire Protection.

In Colfax,resident Jamie Brown ate breakfast at a downtown restaurant Thursday while waiting to learn if his house was still standing.

He evacuated his property near Rollins Lake on Wednesday when "it looked like the whole town was going to burn down." Conditions had calmed a bit and he was hoping for the best.
