“This fire has continued to pose every challenge that there can be on a fire: inaccessible terrain, strong winds, dry conditions. It’s a very difficult firefight,” Berlant said.
Statewide, more than 8,300 firefighters are battling nearly 400 square miles of fires. Many air districts have issued health advisories as smoke settles over Northern California. While Yosemite Valley is clear, the Lake Tahoe basin is thick with smoke, and many outdoor activities have been canceled in Reno, Nev.
The U.S. Forest Service says about 4,500 structures are threatened by the Rim Fire. Berlant said 23 structures were destroyed, though officials have not determined whether they were homes or rural outbuildings.
