A massive California fire ravaged dozens of motorhomes in a Southern California lake on Wednesday after starting from a nearby storage yard, authorities said.

Massive Explosion

The Los Angeles County fire department said witnesses reported the fire shortly after 2:30 p.m. near Canyon Lake. The reservoir is found southeast of the county in Riverside County.

The fire department said about 30 to 40 recreational vehicles were burned and destroyed by the fire and injured a firefighter with non-life-threatening wounds. Officials said no other injury was reported in connection with the fire, US News reported.

Residents could see the towering column of black smoke the fire put out that could be seen from miles away. Authorities were still investigating the origin of the fire but believe that propane tanks could have been involved.
