'High avalanche danger'If all 10 of the missing skiers should perish, the incident would rank among the deadliest single avalanches on record in the United States. The Colorado Avalanche Information Center has tallied six US avalanche fatalities so far this season. The Sierra Avalanche Center had posted an alert before dawn on Tuesday, warning of a "high avalanche danger" in the ski region, the sheriff's statement said. Rescue ski teams were dispatched to the avalanche zone from the Boreal Mountain Ski Resort and Tahoe Donner's Alder Creek Adventure Center. Weather conditions remained hazardous in the Sierra backcountry slopes, with additional avalanche activity expected through Tuesday night and into Wednesday, according to the sheriff's statement.
