Mammoth lakes, California—An avalanche struck the Mammoth Mountain resort Monday and three people suffered minor injuries, an official said. Searchers were trying to determine if there were any other victims.

The Eastern Sierra Avalanche Center had posted a warning of “considerable” danger on Monday.

The avalanche occurred shortly after 2 p.m., said Fire Chief Brent Harper.

More than 200 people were searching an area of a ski run in the Climax section of the resort, which has had record snowfall this season.

The resort was struck by tragedy on April 6 when three members of the ski patrol were asphyxiated by gas from a volcanic vent. One of the three was the resort’s avalanche expert.

The Mammoth Web site reported the resort closed operations for the day at 2:30 p.m. It also said 11 inches of snow had fallen in the 24 hours preceding 6 a.m. and the base depth was 18 feet to 20 feet.

The resort has had more than 52 feet of total snowfall since October
