Orange sky day in the Bay Area was 5 years ago

Do you remember these apocalyptic scenes? Tuesday marks five years since the sky over the Bay Area turned orange.

Several wildfires were burning across Northern California at the time, filling the air with thick smoke that turned the entire sky an orange hue.

One of those wildfires remains the largest fire in California history. The August Complex Fire was sparked by lightning and burned more than 1 million acres.
