A wildfire ignited by lightning is currently burning through a section of California's Sierra National Forest, specifically impacting a grove of giant sequoias in Fresno County. The blaze, which started on Tuesday, has seen firefighters employing specialized techniques to combat the flames, including deploying climbers to extinguish fires in the tree canopies. These ancient trees, some estimated to be 3,000 years old, are receiving additional protection through the use of sprinklers, foil wraps, and strategic clearing operations.
