PHOTOS: That day 10 years ago when ‘cobblestone’ ice froze North Texas in its tracks

A blanket of white covered North Texas on Dec. 7, 2013.

But it wasn’t fluffy snow. It was up to 4 inches of ice and sleet that wiped out power for 270,000 customers and made driving treacherous if not impossible in Dallas-Fort Worth.

The cold snap plunged temperatures below freezing for most of six days — perfect conditions for the “cobblestone ice” that formed across Fort Worth streets and highways.

The slippery bricks were created when 18-wheelers and other large vehicles busted the ice into pieces, which melted into slush during the day and then froze at night, creating a cobblestone effect that stranded hundreds along Interstate 35W from Fort Worth to Oklahoma and I-20 west of Fort Worth, according to the National Weather Service.
