Ten people have died in avalanches across the West in the last 10 days, making this month the deadliest January for slides in nearly 20 years.

The Colorado Avalanche Information Center says 11 people have died in slides this month, including four over the weekend, for a total of 14 so far this snow season.

On Sunday, one person was killed and another was injured in Washington state in an avalanche near the Mount Baker ski area, and two skiers died in Wyoming after being caught in a slide just outside the Jackson Hole Mountain Resort in a popular place for out-of-bounds skiing.

On Saturday, one of three snowmobilers riding in the Whitefish Mountain range near Olney, Montana, died after being buried.
