Colorado-based Brandon Ciullo took footage of the avalanche engulfing Tenmile Canyon, as he drove on the I-70 interstate highway near Frisco, Colorado.
We were driving to Glenwood for a vehicle recovery and saw this huge avalanche on I70.
The video shows the aftermath of an avalanche, which left behind a "cloud" of white.
Later that evening, a second, heavier avalanche caused the same highway to shut down for three hours.
A Colorado motorist had a snow day to remember when he witnessed and recorded the show-stopping moment when an avalanche raced into a canyon on Sunday, filling the adjacent highway with snow. A handful of drivers in Colorado can confirm as much after an avalanche barreled across a roadway this weekend and instantly delivered a complete whiteout. "It's exciting, but pretty nerve-wracking because you don't know when it's going to stop".
"First it was just a big cloud coming down the mountain, then it just turned totally white", he said, according to the station.
Colorado's Transportation Department says it was a natural avalanche and not a controlled slide. His windshield was covered with snow, with visibility temporarily reduced to zero until the barrage of whiteness settled. "Dangerous human-triggered avalanches are very likely".
