A massive blaze engulfed two homes in the Crestline area of the San Bernardino County Mountains Tuesday night leaving both in ruins.
Firefighters responded to calls of a house fire on Chillon Drive southeast of Lake Gregory around 9:30 p.m.
Videos showed arriving firefighters found one house fully involved in fire with flames already spreading to a second home.
Downed power lines sparked and explosions from propane tanks were heard as firefighters attempted to battle the tall flames.
It took crews nearly two hours to extinguish the burning homes and surrounding vegetation that caught fire, according to freelance media firm OnScene.TV.
One person was in unknown condition after being treated for smoke inhalation, OnScene.TV reported.
The cause of the fire remains under investigation.
