STANISLAUS COUNTY -- Several crews fought a vegetation fire west of Patterson in Stanislaus County.
The Rock Fire sparked west of Patterson, around 4 miles up Del Puerto Canyon Road, at around 8:45 Tuesday night.
As of Thursday night, the Rock Fire had burned 2,442 acres in the area along Del Puerto Canyon Road, according to Cal Fire.
It is 100% contained.
Cal Fire Deputy Chief Mike Marcucci said erratic overnight winds pushed the fire toward the Wesley area of Interstate 5.
"The problem is the canyons are very steep, the access is very poor," he told FOX40. "Fortunately, there’s not many homes in the area, there’s not much infrastructure, so we have some room where we can back up a little bit and do some firing and control burns."
The fire is mostly burning in an area where it’s least likely to grow out of control.
"The fire is on the north side of the road. Had it been on the south side of the road, it’s a lot of brush, there’s not a lot of road to stop it," the deputy chief said.
So far, there have been no injuries and no structures are threatened, but acres of ranch land are gone.
"They did lose portions of their land," Marcucci said. "A lot of the land was used mainly as open space. There wasn’t a whole lot of cattle out there due to the steepness of the terrain."
The Cal Fire deputy chief estimates they will be at 100% containment by Thursday evening, however, crews won’t know for sure until Thursday afternoon.
Del Puerto Canyon Road is closed.
"It’s really scary ‘cause where are we gonna go? You know, it’s nothing but highway," said nearby Patterson resident Tracy Hicks.
Crews with Cal Fire and West Stanislaus County have arrived at the scene, along with several brush engines, water tenders and dozers, according to the volunteer firefighters.
