That fire is burning nearly six miles from the Stillwater mine in Sweetgrass county. Officials at the mine say it's business as usual, but they do have an evacuation plan ready to protect the miners. Recent mapping of the fire shows it's burned 580 acres. More than 100 personnel are fighting the fire.

Airtankers and helicopters are also battling the blaze from the air. Lightning started the fire Friday afternoon. A road and area closure is in place in the west fork of the Stillwater river drainage north to Castle Creek.
