A large brush fire near Greenfield had firefighters scrambling to contain it on Thursday.
Cal Fire says they are expecting crews to work into the night to put out the flames.
The Metz Fire is at least 60 percent contained. It started late Thursday afternoon just east of Greenfield in the hillsides near Metz and Topo Roads.
The fire burned 420 acres so far, but a Cal Fire officials says it is likely to grow a little more as firefighters try to climb the hillsides.
"You can see this terrain is very steep. It's too steep to operate dozer on safely, so this is where the fire crews come in handy," said Captain John Spooner, a Cal Fire public information officer.
There were about five crews on scene each with about 15 people and a fire captain. Six air tankers, three helicopters and 13 engines also helped prevent the fire from spreading.
