The Dixie Fire, California's largest, has destroyed multiple structures

The fire, which began July 14, has destroyed 16 structures — residential, commercial and otherwise — Cal Fire officials said in an update Sunday. More than 10,700 structures in Butte and Plumas Counties are threatened.

The Dixie Fire remained active overnight, officials said. It “continues to burn in a remote area with limited access, and extended travel times with steep terrain are hampering control efforts.”

The fire crossed Highway 70 and Highway 89 on Saturday, forcing firefighters to protect the communities of Paxton and Indian Falls. Officials said a damage assessment team will survey the extent of structure damage once conditions are safer.

“Extreme fire behavior is expected again today,” the update said.

The Dixie Fire has forced numerous evacuation orders, including along the west shore of Lake Almanor in Plumas County.

Wildfires burning in Northern California prompted Gov. Gavin Newsom on Friday to declare a state of emergency in four counties, allowing officials access to increased resources.

The declaration included Alpine, Lassen, Plumas and Butte counties, the latter of which was the site of the state’s deadliest and most destructive wildfire in California history in 2018.

The blaze is just one of 86 large wildfires — many of them in the West — burning more than 1.4 million acres across the country, according to the National Interagency Fire Center.

The Tamarack Fire is burning along the state’s border with Nevada and has scorched more than 66,000 acres, per InciWeb, a clearinghouse for wildfire information in the US. It’s 27% contained.

On Sunday, officials announced the sheriff’s offices of Alpine and El Dorado Counties would begin escorting evacuated residents back into the area to retrieve pets and important papers, depending on the fire’s activity.
