RIFLE, Colo. - Fire investigators have confirmed that a wildfire burning north of Rifle on about 991 acres was human-caused.
The precise cause, however, has not been pinpointed.
This fire started next to Highway 13 and was first reported around 1:30 p.m. Wednesday. It actively grew to about 991 acres, fanned by the strong west wind.
Firefighters say they are fully suppressing the Highway 13 Fire, but the rugged terrain is limiting where manpower can be used.
The fire was 60 percent contained by Friday evening, they said.
Because of the topography, three heavy helicopters are working the east and southeast sides of the fire.
Firefighters are working to keep the fire from burning onto the east slope of the Grand Hogback.
Currently, Highway 13 is still open and no structures are in danger.
