(Corona, CA) -- With containment now standing at 85-percent, firefighters are hoping to finish off the 2,600-acre Canyon Fire sometime tomorrow. Some 925 firefighters are mopping up the brush fire straddling the Orange County-Riverside County line, down from 1,900 firefighters sent in after the blaze broke out Monday. The Orange County Fire Authority says four homes were damaged, as were one commercial building and a minor structure.
