A Christmas Eve flash in the sky over northeastern Shasta County has some speculating about reindeer on fire or season's greetings from little green men. But the celestial light show was probably just a meteorite, said Fall River Mills firefighter Quincy Hatch. Hatch and other firefighters were driving east on Highway 299, east of McArthur, to check on smoke from three burn piles reportedly on the Big Valley summit. On their way, Chief Chuck Bethel and others spotted a bright light and an object streaking across the sky about 7:40 p.m., Hatch said.
