Crews battling the Caldor Fire south of Lake Tahoe are facing stiff opposition from both steep mountain terrain and Red Flag Warning weather conditions.
Transporting more firefighters and aircrafts to the Caldor Fire is proving to be especially difficult.
The blaze, which started on Aug. 14, has doubled in size in just 24 hours.
CAL FIRE Ppokesperson Chris Vestal said they are bracing for a long firefight.
"It's tough terrain," he told KCBS Radio. "We're trying to bring the resources in, we have a bunch ordered. When they arrive that will help, however, our bulldozers aren't able to get into all the areas so a lot of this is crew territory, meaning people have to hike in and cut line by hand through some pretty treacherous terrain."
Firefighting airplanes and helicopters are also available, but the smoke and the weather determines whether or not they can fly.
Vestal explained that pilots must be able to see the fire without a heavy smoke cover for CAL FIRE to utilize their crews in the sky.
The Caldor Fire now covers 53,772 acres with 0% containment.
