KNOXVILLE, Tenn. — Here's a record we really don't want to break.

It was Monday, January 21, 1985, and the entire eastern half of the country was in the midst of a brutal deep freeze. Record low temperatures were being recorded across the south.

But no place else in the continental U.S. was colder that day than Knoxville, Tennessee.

The temperatures dipped to -24 that day.

Pipes were bursting all over East Tennessee, including at the city's iconic Sunsphere. The water rushing down the buildings' metal frame quickly froze, covering the structure in icicles.
