Crews have reached 100 percent containment on the the Lower Fire that broke out Saturday afternoon on Lower Springs Road and Eureka Way. The fire torched 110 acres in some of the same area as the Carr Fire six years ago. Investigators are looking into reports that an explosion at a home was the cause, although that has not been confirmed as official. All roads in the area are open, but motorists are still advised to use caution when traveling through the area.
