 Firefighters are working to confine the fire to essentially a large box by burning areas ahead of the fire to sap it of fuel. But firefighters say the terrain is challenging. The fire is burning in a very rugged area of the Wharton State Forest. A lot of it is inaccessible to motorized vehicles or fire equipment. Also at 106 degrees, today has been the hottest day on record in Raleigh-Durham, North Carolina. This is CBS News.
