A man traveling through Colorado’s Rocky Mountains on Sunday morning captured a powerful natural event on his smartphone.

Driving to Glenwood Springs for a vehicle recovery, Brandon Ciullo was on Interstate 70 when he saw an avalanche rip through Tenmile Canyon between Frisco and Copper Mountain.

The interstate remained open after the nearby avalanche.

The Colorado Department of Transportation was doing some avalanche-mitigation work along the I-70 corridor on Sunday, but the agency was not aware of any avalanche-related injuries or closures, a department spokesperson said.

However, I-70 at the Eisenhower Tunnel was closed Sunday as a safety precaution.

The heavy snowfall prompted the Colorado Avalanche Information Center to issue an avalanche warning for the northern and central mountains effective into Monday morning. For a detailed avalanche forecast, go to Colorado.gov/avalanche.
