The Ferguson Fire had scorched more than 4,000 acres of land in the Sierra National Forest, California, and was just 2 percent contained by July 16, according to official reports.

A firefighter, Heavy Fire Equipment Operator Braden Varney, was killed during the response, according to official reports.

The fire caused hazy conditions in Yosemite Valley. Yosemite National Park authorities advised visitors who were sensitive to smoke to “limit any strenuous outdoor activities or plan to visit the park another time.” Credit: Jermaine Parker via Storyful
