Denver International Airport set a new daily snowfall record with 12.1 inches of snow recorded today, breaking the previous daily record of 8 inches set in 2010.
A powerful blizzard on Wednesday left Denver isolated by air and land, and tens of thousands of those stuck at home had no power.
Authorities closed Denver International Airport and Interstate 70. Interstate 25 was closed from Denver north to Loveland and from Castle Rock south to Colorado Springs.
Also in Colorado the NationalGuard are sending five humvees and ten troops to support stranded motorists on I-25.
