From the San Diego Fires, this is some footage of Mount San Miguel which is one of the tallest hills in San Diego County. There are quite a few TV, Radio and Cell Phone Towers. The heat was so intense that it cracked the camera lens of the KNSD-TV live camera mounted on the tower. This footage shows over a 18 hour period of what was happening.
I think the picture speaks for itself. I’d give credit except I don’t know who the photographer is.
