United States

On January 23, 1971, in Prospect Creek Camp, situated near the Arctic Circles along the Alaskan pipeline, the lowest temp ever seen in the United States was -80.1 degrees Fahrenheit (-62.2 degrees Celsius). This was not much milder than the -81.5 °F historic low in North America set on February 4, 1947 at Snag, Yukon, Canada. Tanacross (Alaska) hit -75 °F on a very frigid February day.

On January 20, 1954, near Rogers Pass, Montana, the bottom 48 states of the United States recorded their official lowest temperature of -70 °F. The pass is located in the Rocky Mountains, north of Helena, at an elevation of 5,470 feet (1,667 meters).

The United States is a vast nation with varying temperatures according to state and season. What makes the United States special is that it is both one of the coolest and hottest nations on Earth.
