The fire burning near Interlake and Bee Rock roads was caused by a broken trailer hitch dragging behind a commercial vehicle, Cal Fire spokesman Clint Bullard said.
The hitch broke off, and it and its safety chains dragged behind the vehicle, sparking the fires, he said.
Two of the three original spot fires have since been put out, while the third grew to 50 acres and is still burning.
“We’re hitting it hard, and we’re cautiously optimistic,” Bullard said.
Update 1:40 p.m.:
The fire is up to 50 acres, according to a tweet by Cal Fire.
Road closures are also planned for Interlake and Lynch Canyon roads near Bee Rock.
