In Oregon's Cascade Mountains, an avalanche killed two backcountry skiers, while another was killed in an avalanche near South Lake Tahoe, authorities said.

Another skier, in an avalanche separate from the one in Oregon, was killed near Powderhouse Peak in California, around 111 miles east of Sacramento, according to the El Dorado County Sheriff's Office. On Monday, the victim was reported overdue to the county's dispatch, police said. The skier was later found dead by friends in an avalanche area.
