Eight skiers have been found dead and one remains missing after they were swept away by an avalanche in California. A group of 15 skiers was on a three-day trek organized by Blackbird Mountain Guides into the wilderness at Frog Lake in the Sierra Nevada mountains, near Lake Tahoe. Officials revealed that one of the skiers saw the avalanche and yelled 'avalanche,' before the massive amount of snow toppled the group. #usa #california #lakettahoe #avalanche #skiing
