Firefighters in Northern California are continuing to battle the 3-1 Pit Fire in Lassen County after the fast-moving wildfire burned more than 1,000 acres and prompted evacuation warnings near the Little Valley area.
The fire started Tuesday afternoon near Little Valley Road and Wilson Springs Road, southeast of McArthur. According to CAL FIRE, the blaze quickly expanded from a small vegetation fire into a major wildfire, forcing officials to issue evacuation orders as flames moved through dry grass and brush.
By Wednesday evening, CAL FIRE reported that the 3-1 Pit Fire had burned 1,055 acres and was 20% contained. Earlier evacuation orders were lifted, but evacuation warnings remained in place for nearby communities, meaning residents should stay ready to leave if conditions change.
Fire crews worked through the night to hold the flames inside the existing perimeter. Helicopters supported firefighters from the air, while ground crews continued building and strengthening containment lines. Officials said crews were also patrolling for hot spots to prevent flare-ups.
The fire has created concern for residents in rural parts of Lassen County, where dry vegetation, wind shifts, and rugged terrain can make wildfires difficult to control. Even when progress is made, officials warn that changing weather can cause conditions to worsen quickly.
Local authorities are urging residents in warning zones to stay alert, follow official updates, and prepare important items in case evacuation becomes necessary again. People near the fire area should monitor emergency alerts, avoid closed roads, and give firefighters enough room to work safely.
The cause of the 3-1 Pit Fire remains under investigation.
The wildfire comes as California moves deeper into fire season, with several active incidents burning across the state. CAL FIRE officials continue to remind residents that evacuation warnings should be taken seriously, especially in rural communities where fire behavior can change within minutes.
For now, crews have made progress, but officials say the situation is not over. Firefighters will continue working until the fire is fully contained and the threat to surrounding areas is reduced.
