Avalanche Warnings persist for parts of the Sierra after deadliest US avalanche since 1981

Tuesday's avalanche on Castle Peak, a rugged area in the Donner Pass region of California's northern Sierra, killed at least 8 skiers, officials said Wednesday. The tragedy marks the deadliest U.S. avalanche since the 1981 disaster on Mount Rainier that claimed 11 lives. Avalanche Warnings persist for the region as search and rescue teams attempt to recover the victims and the final missing skier, who is presumed dead.
