SAFFORD, Ariz. (AP) -- Two wildfires burning in the southeastern Arizona mountains remained 80 percent contained Thursday.
Fire crews continued mop-up and rehabilitation along the southern and eastern flanks of the 29,400-acre Nuttall Fire Complex, which is made up of the Gibson and Nuttall fires 15 miles southwest of Safford.
The two fires in the Pinaleno Mountains were caused by lightning in late June.
About 440 firefighters were working on the blaze.
The cost of fighting the fire was estimated at about $9.5 million.
The fires had threatened about 100 cabins in two communities and the $200 million Mount Graham International Observatory before firefighters were able to defend the areas. The communities and the observatory remained evacuated, said Margo Whitt, a spokeswoman for the crew fighting the fire.
Full containment was expected Monday.
