Close
The orange-colored hue in the sky was the result of smoke from the North Complex Fire (including the Bear Fire) and more than 20 other wildfires, which burned more than 2 million acres east of the San Francisco Bay Area.[3] This smoke scattered blue light wavelengths, which only allowed warmer colors to reach the Earth's surface.[4]
