Possible Cause of Grade Fire

Firefighters continue to battle the fire that is at least 900 acres and growing. The wildland fire broke out near Redwood Valley just before 3 yesterday afternoon. Cal Fire said the cause is still under investigation, but there have been witness reports that it was sparked by a pickup towing a motorhome. They both caught fire, which then spread to a nearby hillside. CalFire says firefighters are on the ground and actively working to contain the fire.
