STANLEY - Firefighters made good progress on the Hell Roaring Fire over the weekend and announced Sunday evening the blaze is now 90 percent contained, with full containment expected Monday evening.
The fire more than doubled in size Saturday, growing from 130 to to 320 acres by 8 p.m.
Backcountry hikers and campers were evacuated from parts of the Sawtooth National Forest as the wildfire south of Stanley grew.
The fire started a little before noon on the Fourth of July, about 12 miles south of the mountain town. It is burning mostly in areas filled with downed or dead lodgepole pines.
Fire officials say that although members of the public have been ousted from the forest due to safety concerns, Highway 75 will likely remain open. The fire is no longer burning east to towards the road.
Likewise, most trails and recreation sites in the area remain open, including those at Redfish, Stanley, Alturas and Pettit lakes.
Crews were concerned Saturday's gusty forecast might hasten the westward spread of the fire, but officials reported they were successful in putting in handlines Saturday along the western flank and burnouts to the northeast to quell the expansion.
More than 170 personnel worked to extinguish the fire. along with four helicopters and four engines. Aerial resources assisted by dropping water and retardant.
The fire's cause remains under investigation.
Area closures affect the western side of Hwy 75, including the Hell Roaring Trail, Forest Road 315 (Hell Roaring Road), Forest Road 037 (Mays Creek) and the southern portion of Forest Road 210 from Hell Roaring through Decker Flat.
