Avalanche buries snowmobilers

A snowmobiler, 58-year-old Jon P. LaFramboise, died in an avalanche on the Sierra Madre Mountain outside of Hog Park in Carbon County on March 12

It's the one thing you never want to see when you're in the backcountry. New video shared by snowmobilers shows a mammoth avalanche cascading down a mountainside moments before it buried them.
