A driver and his son are in awe after narrowly avoiding a massive avalanche along a Colorado highway.

The billowing white cloud blocking the horizon was caught on camera from two miles away as the driver slowed their vehicle along I-70 in the stretch between Frisco and Copper Mountain in Ten Mile Canyon.

Jacob Easton told FOX31:

"All of a sudden, me and my dad just saw a big white cloud to the left of us and we instantly noticed the avalanche."

Footage from Mother Nature's fury was posted on Twitter, and it is equal parts terrifying and extraordinary.

Thankfully, they were at a safe enough distance, and the cataclysm posed no immediate threat. While their windshield was plastered from the elements, it wasn't enough to trap them inside the car.

"It's exciting, but pretty nerve-wracking, because you don't know when it's going to stop," Easton said.

Colorado State Patrol reported no injuries or trapped vehicles, but the highway was shut down for three hours – eastbound at Vail, and westbound at Frisco – while emergency service workers cleared the snowy debris.

FOX31 reported an earlier, separate avalanche in the same area that did not reach the highway.

Meanwhile, online, viewers were shouting at their screens as if they were watching a catastrophe movie.

Brandon Ciullo is another witness of the avalanche and posted footage after the white dust had settled and traffic crawled to a standstill.

"It was not a controlled slide. It was a natural avalanche," confirmed a spokesperson for the Colorado Department of Transportation.

The Colorado Avalanche Information Center issued an avalanche warning in most of the Northern and Central Mountains of Colorado through Monday.

They advised drivers to exercise caution particularly when near "steeper overhead slopes."

"A potent winter storm caused avalanche danger to rise yesterday and very dangerous conditions persist today. Large human-triggered avalanches will be very easy to trigger, and some avalanches may release naturally."

This public service announcement reminded drivers to never underestimate avalanches.

While everyone's natural impulse suggested backing up, that's not a wise decision either.

References to Game of Thrones was inevitable.

Please drive safely. And try to enjoy the view, and not be a part of the view.
