The fire, which began Friday in the Klamath National Forest in Siskiyou County, Calif., has burned more than 56,000 acres and prompted evacuations for thousands of people.
The fire sent a huge cloud called a pyrocumulonimbus 39,000 feet into the air. Storm winds, high temperatures and drought conditions helped it grow over the weekend, officials said.
