...firefighters were frantically trying to save the historic astronomical observatory and dozens of critical TV and radio antennas from destruction. By 3 p.m., the fire was approaching closer than ever from two directions: one-half mile to the north and three-quarters of a mile to the west.
CBS has some raw footage of the fire here.
“We expect the fire to hit the Mt. Wilson facilities between 5 p.m. today and 2 a.m. Wednesday morning,” said Los Angeles County Fire Department Deputy Chief James Powers. “Right now, we’re conducting controlled burns around the perimeter in preparation for the impending fire's arrival. We’re also bringing in trucks and special equipment to coat all of the structures with protective gel and foam if necessary. We do not plan to cover everything with a gooey mess.”
