An avalanche in Oregon's Cascade Mountains killed two backcountry skiers while another backcountry skier was found dead in an avalanche field near South Lake Tahoe, authorities said.

A backcountry skier from South Lake Tahoe was killed in an avalanche Monday at California's Luther Pass, the El Dorado County Sheriff’s Office reported. Dispatchers received a call late Monday afternoon of an overdue skier in the area of Powderhouse Peak,

Mammoth Mountain shut down all lift operations on Friday, Feb. 14, after an avalanche on Lincoln Mountain. Two ski patrol workers were caught in the slide.

Three people died in avalanches Monday — one person near Lake Tahoe in California and two backcountry skiers in Oregon’s Cascade Mountains. The avalanche danger was elevated for most of Colorado’s mountains earlier this week but conditions have improved somewhat in some areas.
