Cal Fire personnel began responding to the vegetation fire on North Cow Mountain at around 4 p.m. Sunday, according to a report from Cal Fire spokesperson Julie Cooley.
Cooley said the main fire spread had beens stopped as of 11 a.m. Monday, with crews continuing to work to contain a five-acre spot fire.
By the end of the day, the fire had burned 293 acres and was 45-percent contained, Cal Fire said. What caused the fire still is under investigation.
The firefighting effort was made more difficult and slow by the steep terrain and heavy brush on North Cow Mountain, Cooley said. On Sunday evening several air tankers and air attacks worked the fire because of the remote terrain.
On Monday Cooley said resources committed to the fire from Cal Fire, the Bureau of Land Management, and Ukiah Valley, Potter Valley, Redwood Valley and Hopland fire departments included 370 personnel, 10 engines, 16 fire crews, 6 dozers, two air tankers and three helicopters.
No injuries to firefighters or civilians have been reported, Cooley said.
Full containment of the fire is expected by 6 p.m. Tuesday, with full control by 8 a.m. Friday, according to Cooley's report.
Cal Fire is asking that anyone with information regarding the fire's cause call 707-459-7414.
