At the Pony Fire, almost 5,000 acres have burned, and the communities of Mammoth and South Boulder are still under evacuation order.

Over 300 people are working the fire, and as of Sunday it was at just 10% containment.

The extremely steep and rugged terrain have made it difficult for crews to bring equipment up to fight the fire, but firefighters have been able to start constructing fire lines in hopes to stop it from spreading any more.

The cause of the fire is still under investigation.
