DENVER -- Years ago Colorado's Fraser and Minnesota's International Falls argued over the title, "Icebox of the Nation." In the end, International Falls got the trademark after paying Fraser $2,000 in 1986.

Now several cities in Minnesota are arguing which is coldest.

The CBS Morning Show called it a "cold war" this weekend.

Reporter Bill Geist said, "While International Falls proudly and legally claims the title 'Icebox of the Nation,' and celebrates 'Ice Box Days' every winter. Tower, Minn., holds the state record of -60 degrees, set on Feb. 2, 1996."

But there's another town getting in on the argument, Embarrass, Minn. The official National Weather Service observer there, 77-year-old Roland Fowler, said his thermometer stopped working at 53 degrees below zero that day. However, a visitor recorded an unofficial temperature that day of 64 degrees below zero.

Fowler checks and reports the temperature every day hoping for a new record low. With a thermometer that can go to 100 degrees below zero, he's now ready, he said.

In 2009, Embarrass had the lowest daily temperature in the lower 48 states 24 times.
