Firefighters mopped up portions of the Caldor Fire near South Lake Tahoe, as some evacuation orders near the lake were lifted on September 5.
This video, shared by the Lake Tahoe USFS on September 6, shows firefighters mopping up burning areas. Mopping up consists of extinguishing or removing burning material by “turning it over, stirring it up, exposing it to the air and watering it down until it is completely cold,” according to the USFS.
The Caldor Fire had burned 216,358 acres (about 338 square miles) as of the morning of September 6, CAL FIRE reported, and was at 44 percent containment. Evacuation orders were downgraded for the city limits of South Lake Tahoe, as well as areas north of the city, on September 5. Credit: Lake Tahoe USFS via Storyful
