The Frye Fire, burning in southeastern Arizona, has burned more than 45,000 acres and is 45 percent contained as of Sunday.

The lighting-caused fire is burning steep and rugged terrain on the slopes of Mt. Graham in the Pinaleño Mountain Range.

The fire, which started June 7, has cleared out dead parts of the forest left from the 2004 Nuttall Fire.

So far, the almost 700 firefighting personnel have managed to keep the fire from destroying any of the telescopes on Mt. Graham.

The Area Closure for the Frye Fire includes all campgrounds, roadways and trail systems within the Forest boundary in the Pinaleño mountain range with the exception of State Highway 266 from its intersection at the eastern Forest boundary to its intersection with the western Forest boundary. Graham County Sheriff’s officers will stop any non-essential-fire traffic to maintain safety in the closure area.
