Survivors were able to dig themselves out of the snow and call 911 after skiers unintentionally triggered the avalanche
Four skiers have been killed and four others were rescued near Salt Lake City, Utah, in the deadliest snowslide in the United States in seven years, authorities said.
Two groups of skiers, one of five and the other of three, were in Millcreek Canyon just east of Utah’s capital city when the avalanche was triggered on Saturday, a spokeswoman for the Unified Police Department of Salt Lake City said.
