From KSL news Ryan Hunt saw the avalanche happen around 11 a.m. in Logan Canyon. "All the sudden we come around the corner and there was a truck that just stopped for the avalanche and there was some more snow sliding down behind him," he said.

Drivers didn't wait for help. They started digging out the snow themselves, anxious to make it up the canyon.

"They had sleds and snowboards and little shovels and everything they could think of. I even saw a pan out there," Hunt said.
