Eight skiers that went missing after an avalanche near Lake Tahoe in California have been found dead and one is still missing, authorities said Wednesday. 

Nevada County Sheriff Shannan Moon said during a news conference that authorities have told the families the mission has moved from rescue to recovery.

“They were on their way back to camp when the avalanche actually hit,” Moon said. “It took these search and rescue crews hours just to find those first few survivors that we’re talking.”

The avalanche is the deadliest in the U.S. since 1981, when 11 climbers were killed on Mount Rainier, Washington.

Six survivors were found Tuesday night buried in the snow, Moon said, who described the weather conditions as “extreme.”

The skiers were on a three-day trek in Northern California’s Sierra Nevada as a monster winter storm pummeled the West Coast. Search and rescue crews were dispatched to the Castle Peak area of the Sierra Nevada after a 911 call reporting the avalanche had buried 15 skiers.

Heavy snow and the threat of additional avalanches slowed the rescue effort, authorities said. 

Blackbird Mountain Guides said in a statement said the group, including four guides, was returning to the trailhead when the avalanche occurred.
