The coldest temperature ever recorded in the United States was a bone-chilling -80 degrees Fahrenheit (-62 deg Celsius). This was recorded on January 24, 1971 at Prospect Creek Camp, located near the Arсtic Circle along the Alaska pipeline. The record low for the lower 48 states is not a whole lot warmer at -70 deg F (-57 deg Celsius) on January 20, 1954 at Rogers Pass, Montana at an elevation of 5,470 feet in the Rocky Mountains.
