In about five hours, a fire in the median of Interstate 15 in the Cajon Pass spread over about 3,500 acres of the San Bernardino National Forest. The fire that broke out at mid-afternoon yesterday just north of San Bernardino, forced a shutdown of the main highway between Los Angeles and Las Vegas for several hours. Some structures were threatened in the Oak Hills and Summit Valley communities. Fire officials had no estimate on how many people had left their homes.
The growth of the Cajon Pass blaze slowed after nightfall. About 700 firefighters were involved in battling the blaze in heavy brush and trees that on two occasions jumped across the freeway. Authorities say the fire burned northeastward from Cajon Pass into Cleghorn Canyon, which is lined by dry brush that has not burned since 1994.
