Four firefighters were hospitalized after being struck by a falling tree in Sequoia National Park.
The firefighters had been trying to contain the KNP Complex Fire in Sequoia National Park in Tulare County.
They had to be airlifted out of the fire zone, but have since been released from the hospital.
One firefighter works for Cal Fire while the other three are with California Conservation Corps.
Lightning strikes sparked two fires in September that merged into the KNP Complex Fire.
It's burned 134 square miles, damaged an untold number of giant sequoia tree and is 20% contained.
The fire is also burning in nearby Kings Canyon National Park. Both parks are closed because of the blaze. Firefighters had tried to protect some of the famous sequoias by wrapping their trunks with a protective material.
