Two skiers were killed and one was rescued after they were buried in an avalanche in the mountains outside of Salt Lake City that occurred after several days of spring snowstorms, authorities said.

The Saturday avalanche was one of the most deadly in the state's history. Forecasters had warned of dangerous avalanche conditions.

"Colorado is the home of weak snow and avalanches are not uncommon. This year is worse," the Colorado Avalanche Information Center said Sunday. A snowmobiler in Wyoming also died on Friday.
