ALTA, Utah – Utah Avalanche Center officials are warning skiers after a skier-triggered avalanche at Alta.

According to the Utah Avalanche Center, a skier triggered a “catch and carry” slide Sunday afternoon.

Officials said closed resorts are not performing avalanche mitigation so terrain must be treated like the backcountry.

Authorities said to expect an unsettled week ahead with mountain snow.
