What's the extreme cold weather like in America?

The lowest temperature in all 50 states in the United States was once below freezing point, including Hawaii in the Pacific Ocean. The temperature at the top of Mount Monaque reached minus 8 degrees Celsius. The lowest temperature was recorded in Apa, Minnesota, at MINUS 37 degrees Celsius. According to some meteorologists, the extremely cold temperature in the United States this time is lower than that in parts of Antarctica and even on the surface of Mars.
