The 1967 NFL Championship Game between the Dallas Cowboys and the Green Bay Packers, played on December 31 at Lambeau Field, is known as the Ice Bowl, arguably one of the greatest games in NFL history.
The game was played in brutal cold and windy conditions. The kickoff temperature in Green Bay was -13 F, with a wind chill of 36 below zero. Temperatures were so cold, in fact, that referees had to shout signals so that the metal whistles wouldn't stick to their lips. Even so, nearly 51,000 fans watched the coldest game in league annals.
Several players were treated for frostbite and a fan in the stands died of exposure to the cold.
Bart Starr, the Green Bay Packers Hall of Fame quarterback, scored the game-winning touchdown with 13 seconds remaining, clinching a third straight NFL Championship for the Packers.
