Cal Fire was working on putting out a multi-acre fire in unincorporated Santa Cruz County Saturday afternoon, a fire spokesman said.
Fire crews reported to the fire on Deer Creek Road in Las Cumbres, just west of Los Gatos, at 7:30 a.m., Cal Fire spokesman Daniel Berlant said.
The fire engulfed between 6-10 acres of land.
About 200 firefighters were on the scene at some point Saturday, including helicopters and air tankers, Berlant said.
The fire is burning heavy timber, posing a challenge for crews, Berlant said.
"There's no forward progress on the fire," Cal Fire public information officer Colleen told the Merc. "It's just a matter of time before we have a full line around the fire."
As of 1:15 p.m., the fire is 50 percent contained, and the air tankers have been removed from the site, Berlant said.
The fire is not threatening any structures, Berlant said. No injuries are reported, he said.
Cal Fire said they will remain on the scene through the weekend looking for hot spots.
