The Las Vegas Review Journal a 13-year-old snowboarder on a chairlift was killed in an avalanche at the Las Vegas Ski and Snowboard Resort at Mount Charleston’s Lee Canyon.. The avalanche followed a two-week period that saw an estimated 78 inches of snow fall on the mountain as heavy storms have buffeted the southern California and the Sierras. Locals say this is the worst or second worst storms in memory. Avalanche warnings had earlier been issued for the resort. In February 2004, four skiers were caught in an avalanche at the resort. Three were skiing out-of-bounds, and another man was skiing in an area known as Slot Alley, a side trail for experts. All survived.
