California's Largest Wildfire

That huge fire in California's Sequoia National Forest has now charred about 60,000 acres. Firefighters are exhausted after six days.

They've been able to keep the flames away from the forest's ancient sequoia trees, but officials say the threat is far from over.

They say the fire still has the potential to reach 11 of 38 groves of the trees, some of the world's largest and oldest trees.

The fire is also slowly creeping toward a historic miner's cabin about a mile away. Crews have been clearing the area around the old Speas Cabin.
