Earlier that day, Cole Comstock, 34, of Blairsden, Calif. was killed in an avalanche at another ski resort in the Lake Tahoe area.

The avalanche at Alpine Meadows Ski Resort happened Friday morning after a storm dumped between 11 and 22 inches of new snow in the area.

The Sierra Avalanche Center warned of dangerous avalanche conditions for all elevations following the storm. Its website said there was “a high degree of uncertainty in regards to snowpack instability near and below treeline.”
