The Biscar Fire in Northern California has grown to become the state's largest wildfire of the year, forcing evacuations across more than 300 square miles in Lassen County. The blaze, which began on Saturday, initially covered approximately 4,000 acres but has since expanded dramatically.
By Sunday evening, the fire had consumed 46 square miles, with containment at only 5%, according to the California Department of Forestry and Fire Protection (CalFire). The cause of the Biscar Fire is currently under investigation.
The fire was first reported around noon on Saturday near Snowstorm Road and Vincent Canyon, approximately 24 miles northeast of Susanville. Evacuation orders for the surrounding areas were issued within the first six hours of the fire's ignition.
Caltrans has reported that Highway 395 is closed in the vicinity of the fire, impacting transportation in the region. Prior to the Biscar Fire, the Santa Rosa Island Fire in Santa Barbara, which burned 18,379 acres in May, was the largest wildfire in California for 2026.
Updates on the fire and evacuation orders are being provided by CalFire and the Lassen County Sheriff's Facebook page.
