The Top of the World Fire is burning on U.S. Forest Service lands between Bingen and Lyle, Washington. The fire has burned 170 acres. An air tanker was used to prevent the fire move spreading toward Old Highway 8, SR 14, and private property. A helicopter was used to put out hot spots. Ground crews are working to build containment lines around the fire.
