Side note: Highway 550 in Colorado between Silverton and Durango is also known as the Million Dollar Highway. It's also known as one of the most dangerous roads in America. My family has driven it many times and the lack of guardrails for the steep drops is harrowing especially during the fall and winter months when you never know how slick the roads might be. Avalanches like this are also one of those natural things that can end your life quickly if you're at the wrong place at the wrong time.

Fortunately for these workers, the avalanche was nothing more than a scenic wall of snow they could capture neat video of. Many have not been so fortunate on this highway.
