Skier remotely triggered an avalanche 2'-4' deep, 150' wide and running 1300' vertical stopping just above the highway. This avalanche narrowly missed two travellers below. UDOT LCC triggered 2 wet slab avalanches with explosives 3'-4' deep and 100' wide running 1000' vertical (photo) on a southeast aspect.
