Sutro Tower emerges from orange skies as smoke and ash blocked out nearly all sunlight over San Francisco, California yesterday. This other-worldly glow darkened the city, even in the middle of the day. Scientists say intense updrafts from the blazes have pushed smoke particles as high as 50,000 feet (15,000 m) into the atmosphere. Sutro is a 977-foot-tall (298 m) TV and radio antenna tower situated on Twin Peaks in San Francisco.
